Multiple Inverter Brands

We offer multiple inverter brands in our solution to meet regional ratings and approvals.

Customized EMS

Battery monitoring & diagnostics and IoT data reporting; controllable load parameters for power on/off including microgrid demand, back-up triggers and hourly price schedules.

Applications

Microgreen solutions provide reliable power and energy storage for off-grid regular loads, grid-support cases and emergency back-up, with switchable energy input from renewable energy, a grid connection or diesel generator.


Modular and scalable architecture supports these use cases:

Reliable Off-grid

Day/night, EV fleet plug-in or other load shifting, extending duration from minutes to hours to multi-day periods offsetting renewable intermittency

Grid Support

Smooths renewable intermittency, offsets supply shut-downs, ramp rates, peak management, frequency regulations, voltage support, and rate arbitrage

Back-up Power

Replaces traditional diesel genset with silent, pollution-free solution that reduces GHG emissions
