How To Connect 2 Mppt Charge Controller. The 20A 30A and 40A models are compatible with 12V or 24V systems. Unfortunately it has been raining and cloudy so I havnt been able to see what it can dish out.
The batteries are connected in series. Keep the panels and their wiring completely separate so each controller has its own independent array- in seriesparallel as required to keep the maximum array voltage under the controllers voltage limit but no connections between arrays on the input side of the controllers all. To meet high power charging requirements several solar controllers can be connected in parallel to a battery bank with each controller connected to its own separate PV subarray.
Connect only one temperature sensor and one voltage sense Run synchronized equalisation.
Watch this video to learn WHY and HOW TO setup your MPPT solar charge controllers to charge a si. Then do connection between battery and charge controller. To meet the charging requirements. See the wiring diagram below for the connection between the charge controller and batteries.
