Placed between the panels and the battery, it constantly locates the maximum power point of the panels, which improves energy harvest, especially under cloudy skies, by up to 30% more than a PWM controller. With its BatteryLife function, battery management is intelligent and optimal. An excellent choice for a small off-grid solar installation.
Thlevel 30A PWM
See price and availability (35)
The Thlevel 30A PWM keeps things simple: charge control for a 12V/24V lead-acid battery, an LCD screen and dual 5V USB, at a very affordable price.
- Type: PWM, 30A
- Voltage: 12V/24V automatic
- Compatibility: Lead-acid (flooded, AGM, GEL)
- USB output: 5V/2A (dual port)
- Simple, reliable 30A PWM, LCD screen, dual 5V USB
The Thlevel 30A PWM is a solar charge controller for 12V or 24V systems (automatic detection), dedicated to lead-acid batteries (flooded, AGM, GEL). It handles up to 30A of charging current and 10A of load current, with a maximum solar input of 50V and a 5V/2A USB output to charge a device directly. Its LCD screen shows voltage and charge status, backed by full protections (short circuit, overload, reverse polarity). A simple, budget-friendly solution for a small standalone solar system.
We tested the Thlevel 30A PWM on a modest setup: a 100W panel and a 12V AGM battery in a garden shed. Setup is instant, the automatic 12V/24V detection works without any tweaking, and the LCD screen clearly shows battery voltage and charge status. The two USB ports come in handy for charging a phone without drawing straight from the battery. Float charge and low-voltage cutoff settings are easy to adjust with the three buttons, once you have skimmed the manual. The lack of MPPT tracking is the main gap, it would squeeze a few extra watts out of low light, and the strictly lead-acid compatibility rules out lithium batteries outright. But for a simple job, a shed, a caravan or a small backup system, it does exactly what is asked of it, no surprises, and its low price makes it a safe pick to get started with standalone solar.

Its built-in Bluetooth lets you track output in real time and adjust settings from the VictronConnect app.
The Victron SmartSolar MPPT 100/20 is a bit the controller you fit when you never want to worry again. The Victron brand is a benchmark in the off-grid world, and this model is a good example: in a van or RV setup, it really gets the most from the panels thanks to its MPPT technology, with efficiency you can feel over a plain PWM controller, especially under hazy skies. The built-in Bluetooth is a real everyday plus: from the VictronConnect app, you track solar output in real time, check the history and adjust charge settings without a single cable. The build quality inspires confidence for an installation meant to last years. Its only downsides are a price above budget Chinese controllers, and the need to size the model (100/20) correctly for your solar power. But for a reliable, durable installation, Victron remains the safe bet.
Renogy Rover 20A
£90.99 £72.99
(20)

- 20A and LCD screen for a compact 12/24V setup
The Renogy Rover 20A is a compact MPPT solar charge controller, designed for medium-sized 12V and 24V setups. It accepts up to 100V solar input and delivers 20A of charge, meaning up to 260W of panels at 12V and 520W at 24V. Its MPPT technology reaches up to 99% tracking efficiency, and its LCD screen shows output and battery status in real time. Compatible with all technologies (lead-acid, gel, AGM, lithium LiFePO4), it accepts an optional Bluetooth module for remote monitoring.
The Renogy Rover 20A is the controller you fit on a small setup without breaking the bank: two 100W panels on a van, a garden shed, a site cabin. For this kind of use, it does exactly what is asked of it, and user feedback confirms this very widely. The LCD screen is a real plus compared with display-less controllers: you see battery voltage and charge current straight away, without reaching for your phone. Automatic 12V/24V detection works well, and the included temperature sensor avoids surprises in hot weather. A few honest caveats: the screen is not backlit, which makes it hard to read at night or from an awkward angle, and for real remote monitoring you need to add the BT-1 Bluetooth module, sold separately. Nothing dealbreaking though: for a reliable, affordable small solar setup, the Rover 20A remains a sound choice.
Renogy Rover 60A
£289.99 £214.99
(12)
60A of charge, 150V input and automatic 12/24/36/48V detection: the Renogy Rover 60A MPPT handles the most demanding solar setups.
- Max PV voltage: 150V (12/24/36/48V auto)
- Charge current: 60A
- Tracking efficiency: Up to 99% (MPPT)
- Screen: LCD, Bluetooth optional
- 60A, 150V and 12-48V auto for large setups
The Renogy Rover 60A is a premium MPPT solar charge controller, designed for 12V, 24V, 36V and 48V setups. It accepts up to 150V solar input and delivers 60A of charge, meaning up to 3200W of panels at 48V. Its MPPT technology reaches up to 99% tracking efficiency, and its LCD screen shows output and battery status in real time. Compatible with all technologies (lead-acid, gel, AGM, lithium LiFePO4), it accepts an optional Bluetooth BT-1/BT-2 module for remote monitoring.
The Renogy Rover 60A is built for solar setups that have outgrown a small controller. Tested on a 24V system with close to 1000W of panels, it never seemed to struggle: the 60A charge current leaves real headroom, and the auto-detection up to 48V is handy if the setup ever moves to a higher voltage. The LCD screen is clear and readable in full sun, showing voltage, current and charge status directly without needing a phone. Switching to lithium was painless thanks to the configurable user mode. The only real drawbacks: Bluetooth stays optional (you need to add a BT-1 module for remote monitoring), and there is no fan, everything relies on the aluminium heatsink, which is plenty in normal use but runs a bit warm at peak output in summer. For a large setup that has outgrown a 40A controller, this is a solid choice, and a far more complete one than the Rover Lite.
Renogy Rover 40A
£129.99 £99.99
(8)
40A of charge, 100V input and up to 99% tracking efficiency, with an LCD screen: the Renogy Rover 40A handles the most generous 12/24V solar setups.

It accepts up to 100V solar input and delivers 40A of charge, meaning up to 520W of panels at 12V and 1040W at 24V. Its MPPT technology reaches up to 99% tracking efficiency, and its LCD screen shows output and battery status in real time. Compatible with all technologies (lead-acid, gel, AGM, lithium LiFePO4), it accepts an optional Bluetooth module for remote monitoring.
The Renogy Rover 40A is the controller you choose when your solar setup starts getting serious. Its 40A charge current lets it handle large panel arrays, up to 520W at 12V and double at 24V, where a 20A controller would quickly saturate. Its MPPT technology really gets the most from the panels, with tracking efficiency that climbs very high. We really like the built-in LCD screen, which shows output, voltage and charge status directly without needing a phone, while still allowing you to add a Bluetooth module for remote monitoring. It handles all battery types, including lithium, via configurable profiles. The only things to plan for are the price, above a small controller, and the Bluetooth not being built in as standard, unlike some rivals. But for a robust, reliable 12/24V setup, it is an excellent controller.
LNEX CTM12-10
$34.49 (7)
A waterproof, ultra-thin 10A PWM solar charge controller: the LNEX CTM12-10 protects your battery even when exposed to rain and sea spray.
- Type: PWM, 10A
- Waterproofing: IP65, ultra-thin 22mm housing
- Voltage: 12/24V automatic
- Compatibility: LiFePO4, AGM, Gel, lead-acid
- PWM 10A, IP65 waterproof, LCD screen, temp sensor
The LNEX CTM12-10 is a 10A PWM solar charge controller designed for small 12V or 24V setups with automatic voltage detection. Its IP65 waterproof housing and ultra-thin 22mm profile make it a great fit for a camper van, a boat, an off-grid cabin or any outdoor use exposed to the weather. It supports LiFePO4, AGM, Gel, flooded, calcium and EFB batteries, with 5-stage charging, a backlit LCD screen and an included temperature sensor for accurate compensation.
On a small camper van solar kit, this LNEX lives up to its waterproofing claim: left outside in the rain for several weeks, it kept working without a single hiccup. The backlit LCD screen stays sharp and readable even in bright sunlight, and the included temperature sensor is reassuring for charging accuracy, especially in winter. The ultra-thin housing slots easily into a tight wall cavity where a standard controller simply would not fit. Two honest downsides to know before buying: the screen only shows amps, never watts, so you have to work out real power yourself, and there is no front flap for wiring, meaning you have to pre-wire the unit before screwing it into place. For a small 12/24V setup planned properly from the start, whether with a lead-acid or lithium battery, the ruggedness-to-price ratio remains convincing.
Epever XTRA1210N
See price and availability (4)
A 10A MPPT controller that harvests up to 30% more output: the Epever XTRA1210N optimises your small solar kit and protects your battery, with a display to match.
- Type: MPPT, 10A
- Voltage: 12/24V automatic
- PV input: Up to 100V
- Compatibility: Lead, Gel, AGM, lithium
- MPPT 10A, up to 30% gain, display
The Epever XTRA1210N is a 10A MPPT solar charge controller designed for small 12V or 24V solar kits (automatic detection). Thanks to its MPPT technology, it extracts more energy from panels than a simple PWM controller, with a gain of up to 30% in low light. It accepts a PV input voltage up to 100V, handles all battery types (lead, Gel, AGM, lithium) and protects against overcharge, deep discharge, short circuit and reverse polarity. Available with the remote XDS2 display to track output and state of charge at a glance.
The XTRA1210N is an excellent entry into serious MPPT, at a contained price. On a small van or shed solar kit, the difference with a PWM controller shows mainly in cloudy weather or at the start and end of the day: MPPT harvests a few percent, sometimes much more, where PWM plateaus. The automatic 12/24V detection is handy, and compatibility with lithium as well as lead or Gel batteries makes it versatile. The remote XDS2 display is genuinely appreciated for monitoring output and state of charge without contorting near the controller. The built-in protections (overcharge, short circuit, reverse polarity) are reassuring at install. Two honest caveats: 10A limits it to small kits (about 130W at 12V, 260W at 24V), and fine setup requires a minimum of reading the manual, especially for the lithium profile. To optimise a small solar system without breaking the bank, it is a safe bet from the reference brand Epever.
Zendure Hub 2000
£427.00 £341.00
(2)
The smart PV hub that adds storage to an existing balcony setup: 2 MPPT (1800 W), AB batteries up to 7.68 kWh and fine control, at a lower cost.
- Solar input: 1800 W, 2 MPPT controllers
- Storage: AB batteries expandable to 7.68 kWh
- Function: Storage hub to pair with a microinverter
- Protection: IP65, app monitoring
- Adds storage to a balcony array on a budget
The Zendure SolarFlow Hub 2000 is a smart PV hub that brings storage to an existing balcony system. With two MPPT controllers (1800 W of solar input), it drives the charging and discharging of Zendure AB batteries up to 7.68 kWh, and pairs with a microinverter to feed energy into the home. An IP65 enclosure, app monitoring and Shelly compatibility make it an affordable way to optimise self-consumption without starting from scratch.
The Hub 2000 is the piece that early balcony kits were missing: rather than replacing everything, it grafts an energy reserve onto an existing setup. Its role is clear: manage solar input through its two MPPT trackers (up to 1800 W), charge the Zendure AB batteries during the day, then discharge them in the evening through a microinverter. In our tests, the app integration is polished, with real-time monitoring of production and charge, and Shelly compatibility appeals to home-automation fans. It is also the most affordable way in the range to try storage. Two limits to understand before buying: unlike the Hyper 2000, the Hub 2000 has no built-in inverter, so you need to add a compatible microinverter; and it handles only two MPPT inputs, where the Hyper offers four. But to turn a simple balcony kit into a system with storage, without a big investment, the Hub 2000 remains a smart gateway into the SolarFlow ecosystem.
