The 506KTL has been given virtual inertia, power oscillation damping and a black start function, which are the services that grid operators usually expect from battery storage, within a single 420 kW string inverter.
According to the comparison on WattPower's booth screen, the new unit delivers 145 kW more than the 330 KTL at 50°C, while its AC output has been raised from 800 V to 1,000 V.
For commercial and industrial customers, the company links its inverter to a smart logger, a power sensor and a cloud platform, so that site owners can match their solar output against their load in real time.
