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
- Charges at 20 A: onto a 12 V or 24 V bank that the unit sets itself to as 12V/24V (Auto)
- 280W of panel on 12 V, 550W on 24 V: the two array budgets that a 20 A rating allows
- Array voltage accepted to 95V: starting once PV reaches the 15V start-up voltage
- An MPPT window of 15-80 VDC on 12 VDC: and 30-80 VDC on 24 VDC, converting at up to 98%
- 3-Step charging corrected -5 mV / °C / cell (25 °C ref.): applied over the 0 °C to +50 °C range, with surge protection rated 4500 Watts / port
- 0.9 kg in a 240 x 170 x 102 mm case: IP20 (indoor & vented) for indoor wall-mount, working 0°C to 55°C
- 30 A MPPT charging: Tracks the array's maximum power point and delivers up to 30 A into the battery bank.
- 420 W at 12 V, 830 W at 24 V: Accepts 420 W of PV array on a 12 V bank or 830 W on a 24 V bank, under a 95 V input ceiling.
- Automatic 12 V / 24 V detection: Reads a 12V/24V (Auto) bank and tracks from 15-80 VDC at 12 V or 30-80 VDC at 24 V, starting at 15 V.
- Temperature-compensated charging: 3-Step charging with -5 mV / °C / cell compensation referenced to 25 °C and applied from 0 °C to +50 °C.
- 4500 Watts surge protection: Transient surge protection of 4500 Watts per port inside an IP20 indoor, vented enclosure.
- 1.06 kg wall-mount unit: 240 x 170 x 102 mm and 1.06 kg, with a built-in LCD and 98% maximum conversion efficiency.
Frequently Asked Questions
How many amps will the SCCM2024-II push into a bank?
20 A. That is what the SCCM2024-II pushes into a 12V/24V (Auto) bank, charging in 3-Step at up to 98% conversion.
How much PV can the SCCM2024-II carry?
280W behind a 12 V bank, 550W behind a 24 V one. Array voltage must stay under 95V, tracking opens at 15V, and the window is 15-80 VDC on 12 VDC or 30-80 VDC on 24 VDC.
Where does the SCCM2024-II mount, and what does it measure?
240 x 170 x 102 mm and 0.9 kg, on an indoor wall. The IP20 (indoor & vented) case works 0°C to 55°C at 0~90% (No condensation), with storage at -25 °C to 75 °C.
Does the SCCM2024-II support MODBUS communication?
CAN (parallel), RS485 (BMS) and built-in WiFi are the interfaces the SCCM2024-II carries, read locally on an LCD (built-in). Each port also carries 4500 Watts of transient surge protection.
How many amps does the SCCM3024-II charge at?
30 A is the maximum charge current, delivered into a bank the controller reads automatically as 12V/24V (Auto) at up to 98% conversion efficiency.
What size solar array can the SCCM3024-II take?
420 W of array at 12 V or 830 W at 24 V, with open-circuit voltage never above 95 V. Tracking begins at 15 V and the MPPT window is 15-80 VDC on 12 V or 30-80 VDC on 24 V.
What are the dimensions and weight of the SCCM3024-II?
240 x 170 x 102 mm and 1.06 kg, wall-mounted indoors, with a built-in LCD for status.
Can the SCCM3024-II be installed outdoors?
IP20 (Indoor & Vented) is the enclosure rating, so it is an indoor wall-mount unit. It operates from 0°C to 55°C at 0~90% humidity with no condensation, and stores from -25 °C to 75 °C.
What is the maximum charge current of the SCCM4524-II?
45 A. The SCCM4524-II pushes that into a 12V/24V (Auto) bank whose voltage it sets for itself, converting at up to 98% maximum efficiency.
How many watts of panels can I put on the SCCM4524-II?
1250 W on a 24 V bank, or 625 W on 12 V. Both sit under the 95 V maximum solar input voltage the SCCM4524-II accepts, and tracking begins at 15V.
