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 Morocco that is ONEE Morocco. Confirm the grid code, import requirements and any local certification with them, or with us, before you order.
Key Features & Technical Highlights
- Nine-certificate dossier: UL1973, UL9540A, IEC62619, VDE2510-50, CEI 0-21, FCC, UK, CE and UN38.3 in one module.
- All 5.12 kWh usable: Usable energy is listed at the full 5.12 kWh, with a recommended depth of discharge of 90%.
- Doubled current budget: 100 A continuous charge and discharge - twice the standard SE-G5.1 - with a 150 A peak.
- Optional cold charging: Standard charging runs 0-55 degrees Celsius, with an optional extension down to -20.
- 125 A two-pole breaker: A built-in 125 A 2P 60 Vdc circuit breaker protects the DC connection.

Frequently Asked Questions
Which certifications does the SE-G5.1 Pro-B hold?
UL1973, UL9540A, IEC62619, VDE2510-50, CEI 0-21, FCC, UK, CE and UN38.3 - the list projects with formal safety documentation usually require.
Can the SE-G5.1 Pro-B charge in freezing weather?
Standard charging covers 0-55 degrees Celsius; Deye lists an optional -20 charging capability for this model, and discharge already spans -20 to 55.
What makes the Pro-B different from the standard SE-G5.1?
Twice the continuous current (100 A versus 50 A), usable energy listed at the full 5.12 kWh, a 10-year stated warranty instead of 5, a far longer certification list and a 125 A two-pole breaker.
How large can a bank of SE-G5.1 Pro-B units be?
Sixty-four in parallel - 32 without external equipment - for a stated maximum of 327 kWh.
What electrical window does the SE-G5.1 Pro-B operate over?
43.2-57.6 V around a 51.2 V nominal - the low-voltage inverter class - with humidity tolerance of 5-95%.
