ESS (Energy Storage System)

Our ESS is designed and produced for residence house application and for small capacity facility. Up to now our ESS maximum capacity is 5 KVA and has two version.

One is DC 168V / AC 110V or 220V and the other one DC 48V / AC 110V or 220V.

The features of our ESS is as follow.

Grid –on /off system : it can use with grid-on position, grid-off position and grid-on/off combined position as well.

Depends on your setting, ESS can do daytime discharging and nighttime charging. Or opposite position operation is also possible. Regardless this operation, if the electric grid supplying is failed, ESS automatically & immediately supply electric energy. So, our ESS is free in & out from grid supplying and it is grid on-off system.

Using pure-sign wave: different from modified sign wave, it doesn't give any damage & noise to electric motor. So, there is no problem to use fan, refrigerator or others.

Installed several kinds of battery charging algorism: depends on battery type, it has their own charging algorism and our ESS is equipped AGM battery, tubular battery, lithium battery and even car battery algorism as we are industrial battery manufacturer as well.

Instant power supply: 168V system is equipped UPS function and 48V system only request 3~4 sec to supply electric energy again when grid-supply failed.

Smart function on 168V system: for example, if the ESS is set as 2KW and the demand is less than 2KW, ESS supply electric energy from the battery bank. However, if the demand is increased for example as 3 KW, ESS supply electric energy from 2KW from battery and 1 KW. Combined energy is mixed & supplying. After demand is down less than 2 KW again, ESS automatically cut grid connection and supply energy continuously from battery bank.
