One SCCM30-120-III platform covers 30, 45, 45, 60, 80, 100 and 120 A of maximum charge current.
95 V on the 30-45 A models, 145 V on the 45-80 A models and 165 V on the 100-120 A models.
Maximum PV input power at 12V rises with the rating, and tracking starts from a 20 V PV start-up voltage.
The tracking range widens with the rating, converting at up to 98% maximum efficiency.
Bulk, absorption and float hold 14.40V absorption and 13.6V float on a 12V flooded bank.
Referenced to 25°C and active from 0°C to +50°C, inside an IP20 vented enclosure rated 0°C to +55°C.
The Felicity Solar SCCM30-120-III is an MPPT solar charge controller published in seven charge ratings — 30, 45, 45, 60, 80, 100 and 120 A — with 98% maximum efficiency, 3-step charging (bulk, absorption, float) for flooded batteries and a 20 V PV start-up voltage. Maximum solar input voltage climbs with the rating: 95 V on the 30-45 A models, 145 V on the 45-80 A models and 165 V on the 100-120 A models, while the MPPT window on a 12V battery widens from 18-80VDC to 18-145VDC. Maximum PV input power at 12V runs from 420 W on the smallest rating to 1650 W on the largest. Charging holds 14.40V absorption and 13.6V float with -5 mV/°C/cell compensation referenced to 25°C, active from 0°C to +50°C. CAN parallels units, RS485 carries BMS traffic and WiFi is built in, all read on the built-in LCD. The IP20 vented enclosure wall-mounts indoors and runs 0°C to +55°C at 0-90% RH, non-condensing. We are an authorised Felicity Solar distributor and supply the SCCM30-120-III from our own stock. Warranty: 2 Years.

30 A to 120 A, depending on the rating you order: the SCCM30-120-III is published in seven charge ratings — 30, 45, 45, 60, 80, 100 and 120 A — so 120 A is the top of the range, not a figure every unit delivers.
200x137x65 mm on the smallest rating up to 329x219x118 mm on the largest. The seven published sizes are 200x137x65, 221x151x80, 276x184x100, 276x184x100, 289x198x103, 329x219x118 and 329x219x118 mm, one per charge rating.
Flooded batteries at a 12V nominal system voltage: absorption is held at 14.40V and float at 13.6V, with -5 mV/°C/cell temperature compensation referenced to 25°C and active from 0°C to +50°C.
No — the enclosure is IP20 (indoor and vented) and the unit is an indoor wall-mount. It operates from 0°C to +55°C at 0-90% RH non-condensing, and stores from -25°C to +75°C. Warranty: 2 Years.
