85W eArc solar panels are 9V. There are two options to charge a 12V
battery:
Two panels can be wired in series to create 18V, then wired to a normal PWM or MPPT solar controller such as a [Victron 75/15 MPPT SmartSolar] or [Victron PWM USB & LCD 20A]
A voltage boosting solar controller can be used (note boost controllers are rare and expensive) - such as a Genasun GVB model
Some REDARC units such as the BCDC12XXD and Manager30 can charge from 9V solar panels, so one panel will function with those controllers (please check your manual first to confirm)
