This 10A dual battery solar charge controller is designed for independent charging of 2x12V or 2x24V batteries / battery banks. The controller uses PWM (Pulse Width Modulation) technology which increases charge acceptance and extends the life of your batteries. PWM technology can also recover some lost battery capacity.
This is a perfect solar controller for a caravan, motorhome, boat or another system with 2 separate batteries (e.g. engine and leisure battery). Initial charging priority can be set e.g. 80% of power to the engine battery and 20% to leisure battery. When one of the batteries is fully charged the controller will automatically divert all power to the other battery.
The unit can also work with a single battery. If there's only 1 battery connected, the controller will automatically charge it at full power. Second battery can be added later.
This controller can work with solar panels with combined power up to 160W (12V) / 320W (24V). It has many protection functions, such as reverse current, over charge, short circuit, reverse polarity etc. Other features include LED indicators, battery type selection (sealed, gel, flooded), temperature sensor and RJ-45 socket for a remote LCD meter (purchased separately).
- Fully automated operation and auto 12/24V
- 3 pairs of terminals (input, battery 1, battery 2) for wires up to 4.0mm2
- LEDs to indicate state of charge
- Temperature compensation -30mV/C/12V
- RJ-45 connection for a remote meter (not included)
- Full electronic protection
- Self-consumption: 4mA at night, 10mA when charging
- Working temperature: -35C to +55C
- Size: 15.5 x 7.6 x 4.0 cm
- Weight: 185 g

This controller charges both systems at the same time and is entirely configurable to your specific requirements. You can give either battery system priority and the unit will charge at that rate until the prioritised battery is full, it will then swap the entire charge to the second battery system automatically. Set up for the unit ( battery type - lead/acid, gel, or sealed) is easy using LEDs on the unit as is setting the priority for the individual system from 50/50 to 90/10.
All the instructions are included in the box.
I use the unit on a narrow boat with domestic batteries (3 x 110 a/hr) and a starter battery (1 x 110 a/hr) and I am using a 35watt solar panel. All feeds ( panel to controller and controller to each battery bank ) are individually fused and the controller takes care of the rest. I set up the unit to charge the starter battery first and then the domestic batteries
Altogether a very elegant solution and what's more, IT WORKS!!
Shame that the addon meter is so expensive and no info about the comms protocol so you can't make your own - hence knocking one star off. Otherwise perfect.
The motorhome came with a 100 watt solar panel fitted and during my tours last summer I had no problems running electrical items despite extensive stays on sites with no electric hook-up. Of course this was helped by the fact that I have two leisure betteries connected in parallel.
The problem arose when the vehicle was laid-up for the winter and I realised that the solar panel was only connected to the leisure batteries and not the vehicle battery. I tried using an electrical hook-up on my driveway and then realised that the built-in battery charger was also only connected to the leisure batteries.
So the vehicle battery was constantly draining and this was not helped by the alarm system that was fitted. I did some research and discovered that vehicle batteries in particular can be permanently damaged by allowing them to discharge too much. Leisure batteries are not affected so much as they are designed differently and are described as "deep discharge" batteries.
I initially solved the problem by connecting a C-Tek battery charger to the engine battery but I didn't like leaving an extension cable draped across my drive and this problem could be even worse for those people who use remote storage facilities for their motorhome when it's not in use.
I also resented the fact that I already had a perfectly good solar panel producing electricity every day during daylight hours.
So the answer seemed to be this dual solar charge controller.
I took the opportunity of relocating the charge controller to a point nearer the batteries. This is recommended as there is a voltage drop in the cabling. The existing controller was situated in a wardrobe directly under the solar panel but about 5 metres away from the batteries.Read more ›
