Real-World Installation Projects
Our solar-storage inverters power residential, farm and small-commercial sites for backup & off-grid energy needs.

Compact home solar-storage backup solution for daily household loads. Fast power transfer, low noise, protects home appliances from blackouts and voltage instability.

Reliable off-grid power for remote farms with poor grid access. High overload resistance, tough for outdoor harsh conditions, supports irrigation & farm equipment.

Multi-parallel inverter backup solution for factories. Flexible capacity expansion, stable commercial-grade output, avoid production losses from power outages. Request real-world local project references. Contact us for case studies for your region.
It can work in grid-tied mode without battery. For off-grid backup function, battery is required.
Mainly compatible with LiFePO4 battery, also support lead-acid battery.
Standard version does NOT support parallel connection. Models with suffix P support up to 9 units in parallel for power expansion. Do NOT mix standard and P units in one parallel system. Their mechanical dimensions and weight are slightly different.
Yes, the whole SYP series accepts generator as AC backup source. Transfer time under GEN mode is 20ms, longer than 10ms of UPS mode. It works well for off-grid areas without utility grid.
