Off-Grid Solar Inverters

An off-grid solar inverter powers loads from solar panels and batteries without any connection to the public grid. It suits remote sites, rural homes, farms, telecom stations and any location where the grid is absent or unreliable. The company FAQ names off-grid inverter series including AN-SCI-PRO, described for off-grid use, and AN-SCI02-PA, described for off-grid parallel use. No single-model specification table has been published for either series, so this page does not present a model specification.

An off-grid system has three parts that must be sized together: the panel array, the battery bank and the inverter. The inverter must handle the peak power of the loads it serves, including the starting surge of motors and pumps, which can be several times their running power. The battery bank must store enough energy for the nights and cloudy days the site must survive. The panel array must recharge the bank in the available sun. Sizing any one part without the other two leads to a system that either runs out of energy or costs more than it needs to.

Buyers considering an off-grid inverter should list their loads with wattages and running hours, state whether any load is a motor or a pump, and state how many days of autonomy the system must provide. With that list, the inverter and battery can be sized from real numbers rather than from a guess. No price or delivery time is published for this category, and none is stated here.
