Sizing Guide for Solar Charge ControllersWednesday, 3 August 2016 | Admin Sizing guide for solar charge controllers We stock a wide range of both PWM and MPPT solar charge controllers. The majority of charge controllers are designed to work on both 12V & 24V battery systems; they will automatically detect whether your battery configuration is 12V or 24V. We also stock a small range of MPPT solar charge controllers that are capable of work on 36V & 48V battery systems. Each manufacturers charge controllers may differ slightly in what their capabilities are, in terms of Voltage & Watts input and along with the amounts of Amps they can handle. When choosing your solar charge controller, make sure it is compatible with your battery i.e. standard sealed lead acid leisure battery, AGM, GEL or even Lithium. The majority of standard PWM and MPPT solar charge controllers we sell are capable of running the above battery types but not lithium. If you are running a 24V battery systems (2 x 12V battery connected together in series), you can usually double the input of the solar panel input. However please be aware to check the maximum voltage input of the solar charge controller, to make sure you do not overload it. The charge controller you require will depend on the number and type of panels you wish to run.
