Protection Function
1. Battery reverse protection: the system will don't work after the battery reverse connection, but the load has a
negative voltage output.
2.solar panels reverse protection: The system don't damage after solar reverse contact
3. Overload Protection: 1.25 times the rated current for 30 seconds,1.5 times the rated current for 5 seconds overload protection.
4. Overload short current protection: ≥3 rated current.
5. Anti-reverse charge protection at night: the evening to prevent the battery discharging through the solar panels
6. TVS Lightning Protection
7. Moisture treatment: three anti-paint treatment of imports
8. Input Fuse: 25A
1.5 Short-circuit discharge
1. After Short-circuit protection, Long time press key will release the short-circuit state.
2. After Short-circuit protection, every 4 hours release one time. 3. After Short-circuit protection, automatic release at the next night.
