Overview

Reliable power when the grid cannot be relied on

22kW Solar System for Off Grid combines solar generation, battery storage and the main system components in one coordinated package. It can keep essential equipment available through outages and reduce routine dependence on diesel generators.

A guesthouse can keep reception, room lighting, WiFi, refrigeration, water supply and selected comfort loads available when grid power fails.

How to plan loads around 22kW

Keep these loads running

Guest rooms, reception, lighting, WiFi and security; Refrigerators, freezers, office equipment and POS systems

Choose the system around the equipment you want to keep running at the same time during an outage.

Water pumps, selected air conditioning and other managed motor loads after surge checks

These loads can be included after we check their running power, starting power and normal operating schedule.

Tell us if you need these too

Several large air conditioners, electric kitchen or laundry heating, large pumps or workshop machinery

If you want to run these loads together, tell us before quotation so the inverter, battery and solar array can be sized for them.
