INV-G1618 / G1645 Off-Grid Inverters
Pure sine wave off-grid inverters with parallel capability. Twelve units on one communication cable gives 144 kW continuous — enough for a village microgrid without a central inverter.

Why Parallel on One Cable
Conventional multi-inverter systems need a communication hub and careful phase balancing. The G1618 series synchronises over a single cable and self-assigns master/slave roles. Adding capacity means adding a unit, not replacing a central inverter.
