I am looking for a proper solution to interconnect 2X20 KVA UPS with 50 KVA Generator to common load with autoswitchover. In the absence of coomercial AC the UPS should take the load for few minutes; therafter the genset should start and take the load from UPS without break. And, reverse while the AC power is restored. UPS is already installed and working but we need more backup so we want 50 KVA Genset in the circuit. Pls. suggest proper solution.
