SunCumulus Premium Pro
3 Phase Energy Export Solar ESS 4.8 kW – 240 kW
3 Phase Self-Consumption Solar ESS
4.8 kW – 240 kW
An MNRE-approved, IEC and EN compliant, Wi-Fi enabled ESS designed to provide high efficiency while handling heavy loads in tough conditions. Its smart algorithms enable cost reductions by supervising peak demand, more revenue by exporting to the grid while charging battery, and plug-and-play installation due to insensitivity to input grid phase sequence.
