Thunderbolt 30 amp solar charge controller
Thank you for selecting the SMK MPPT solar charge controller. The SMK MPPT series controller is an advanced maximum power point tracking solar battery charger. The controller features a smart tracking algorithm that finds and maintains operation at the solar array peak power point, maximizing energy harvest. Just bought the HF 45W kit. I agree, the controller is kinda cheesy. Would a 20 Amp, 12 Volt charge controller be sufficient? Reason I am asking is the HF optional accessories card shows a 30 amp, and I already have a 20A controller. Also, if you charge two 12vdc batteries (in paralell) does it take twice as much time as just charging one?
