About the Felicity Solar SCCM4548-III Solar Charge Controller

The Felicity Solar SCCM4548-III steps up to a 12-48V battery bank, pairing 45A of charge current with a wider 18-125V MPPT window, a 145V input ceiling and up to 2500W of panel input at up to 98% efficiency with 3-Step charging. It supports AGM, Gel, Flooded, Lithium and user-defined battery types, communicates over RS485, CAN, MODBUS, Bluetooth and WiFi, and weighs 3.3 kg in a wall-mounted IP20 enclosure. We are an authorised Felicity Solar distributor and supply the SCCM4548-III from our own stock, with technical support before and after the sale. The enclosure measures 276.4 x 184.4 x 100 mm with an LCD display for local monitoring, and its step up to a 12-48V bank suits a residential or small commercial installation needing 48V headroom that the 12V/24V SCCM3024-III and SCCM4524-III do not reach.
