Yes. PICO and PICO+ battery monitors can monitor up to 6 electrical systems (battery banks) at the same time. Each system can be on different voltage level. For each electrical system (battery bank), an Active Shunt is needed. At this time, we support 12V, 24V, 48V, 60V and 72V (using SC302T shunts) and 12V and 24V (using SC300 and SC500 shunts).
