Figures on this page are the manufacturer's own, measured at the test conditions the datasheet states — they do not change by country. What changes is the approval that has to be met before the unit is energised: in the UAE that rests with the local authorities (DEWA, ADDC, SEWA). Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
Key Features & Technical Highlights
- Seven charge ratings, 30 A to 120 A: One SCCM30-120-III platform covers 30, 45, 45, 60, 80, 100 and 120 A of maximum charge current.
- Solar input accepted to 165 V: 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.
- 420 W to 1650 W of array at 12V: Maximum PV input power at 12V rises with the rating, and tracking starts from a 20 V PV start-up voltage.
- MPPT window of 18-80VDC to 18-145VDC at 12V: The tracking range widens with the rating, converting at up to 98% maximum efficiency.
- 3-step charging for flooded batteries: Bulk, absorption and float hold 14.40V absorption and 13.6V float on a 12V flooded bank.
- Temperature compensation of -5 mV/°C/cell: Referenced to 25°C and active from 0°C to +50°C, inside an IP20 vented enclosure rated 0°C to +55°C.
Frequently Asked Questions
What is the maximum charge current of the SCCM30-120-III?
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.
How big is the SCCM30-120-III charge controller?
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.
Which batteries does the SCCM30-120-III charge?
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.
Can the SCCM30-120-III be installed outdoors?
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.
