Product Description

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).

Specifications:

- 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

The item is packaged in the original colour factory box and comes with a user manual.

I have been looking for a similar item for a long time, most of the controllers give you a controlled output and a constant output, so you could only charge one battery system in a controlled manner at a time, I needed to charge two separate battery systems his meant regularly changing the connections over.
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!!

Ideal for use on boat with two batteries. Arrived promptly and seems to work exactly as described in the instructions. Had to source some extra bits of wire and connectors - you may have various odd terminals on your battery and/or the changeover switch were you will connect the feeds. You should fit an inline fuse in each battery positive wire, also I prefer to have a plug/socket in the lead to each battery so that I can quickly disconnect the charge controller without having to mess with screws or battery terminals - for each battery get a standard solar panel extension lead with a connector at each end (Maplin had one, couldn't find on Amazon) and cut it in half to make two tails to go to controller and the battery terminals.
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.

I bought this for use with my 2012 Autoroller motorhome.
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.

This is a robust and reliable controller. It will control any solar panel up to 20 amps output and controls the charge to two batteries, vehicle and leisure. You can adjust the level of charge required for the primary battery before splitting the charge to the two batteries. It is easy to install and to set up.

SMOKE.I replaced my existing charger and followed the instructions for the new one then left it running for about 15 minutes. I left my van and went inside the house to get a cup of tea and when I returned I was shocked to find it was full of acrid smoke and the smell of burning plastic! Good job that I didn't go out that morning or things could have taken a turn for the worst. The fusing for the circuit was 7.5amp and it was still intact.I contacted the seller via Amazon, sent the unit back and had a refund with no problems. I am disappointed that that unit failed, It looked like the perfect solution but I will not be replacing it with the same thing. I have had no communication from the seller at all throughout.

I bought this as I wanted to charge my leisure battery on my van and also my van battery via the solar panel . You can set it to charge your leisure battery say at 80% and your van battery at 20% or at any % you want, but if you have a intelligent voltage sensing relay you don't really need a dual controller as most sensitive split chargers work both ways, eg on my van as soon as my leisure battery gets to eg 13.3 volts the voltage sensing relay will conect the 2 batteries together so the solar panel will then charge the 2 batteries until the voltage drops to whatever you voltage sensing relay is set, eg mines is 12.8 and I've checked this over and over with voltmeters and it works perfect so now I just use the one battery outlet on the solar controller connected to my leisure battery and I'm very pleased with the way it works. But you can still use the second battery outlet to charge other batteries if you wanted to keep them completely separate from your van and leisure set up.
