Review on Vehpro Solar Panel Charge Controller MPPT 40A-100A 12V/24V Auto Tracking with Dual USB Ports (100A) by Quvarious Morrow

Ok, the instructions are confusing and not useful. The clamps are only for max. 12 ga or 20 AMP. PWM controller, not MPPT. Therefore, the panels and the battery must have the same voltage. Panels 12V (18V) battery 12 (12.6V). Aside from that, it should cost $15 and PWM. It is not UL and must be kept in a dry case. After two weeks I can't say it has battery overcharge protection. If you have one, here is how you need to connect it. The panel is designed for solar panels. Please install a fuse between the panel and the controller and use a blocking diode when using more than one panel per panel. Battery - battery and inverter. The inverter draws more amps than a safe controller run in my opinion. Please fuse Blub is power for lighting 20 amps (12V*20=240W max) fuse again. - NoSystem single battery and panel is ok.
