Photonic Universe 20A MPPT solar charge controller / regulator with built in LCD display for solar panels up to 260W (12V battery system) / 520W (24V battery system) up to 100V

I have used solar for many years, recently putting 2 * 100W panels on my caravan roof, for off grid caravanning. Caravans often come with small cheap panels with inferior PWM charge controllers, these are nearly always for battery maintainance so that trackers and alarms still function. This 20A MPPT controller will ensure your batteries are topping up with every last bit of energy your panels are creating, this is important if you plan to caravan off grid, but only really work efficiently with a matched pair of panels linked in series. On an average summer day I can easily achieve peak input of 8-12 amps per hour. It's a great price for a great product, however the additional MT50 display is really a must to help you monitor your consumption vs input

Exceeded my needs and expectations. Very good charge controller. I installed this on my 150W caravan system and it works extremely well. I have paralleled leisure batteries totalling 225ah and they recharge from 60% before the sun is properly up. On overcast days, the recharge is about an hour longer. Probably an overkill for my needs but...…. 'buy cheap, buy twice!'

I bought for my motorhome, with 2x 100w solar panels. When you see the size of the controller, your jaw will likely drop as mine did!! It's a full fledged controller than you could use at home to power your house from your solar array!Lots of options and configurations, and the manual is very descriptive.

Works well and has plenty of features
