Advantages

Less voltage impact on front-end equipment;
- Input TDHI is less than 3% and input power factor reaches 0.99.
- The system has a delay function once the power is switched on, so that causing less voltage impact on front-end equipment such as generator and etc. in order to reduce machine overloading.
Multiple charging modes for battery protection;
- Two-stage battery allows charging protection.
- Auto temperature compensation to ensure longer battery lifespan.
- Optional battery capacity expansion for extra charging demands.
- Auto battery aging test for safety assurance.
- Cycle charging strategy is able to maintain your battery condition to prolong the lifespan.
- The system test-charges the battery in case the battery voltage is inconsistent after replacing.
The inverter capacity is enlarged to ensure long-term operation in 115% work load (power factor 0.8);
No matter the back-end load belongs to 0.9 inductive load or 0.9 capacitive load, the active (real) power will not decrease;
Overall efficiency is larger than 95%;
DSP (digital signal processor) ensures signal static/dynamic features for micro-processing during system operation;
Multiple intelligent communication methods realize remote management.
