Application Scenarios

This product is linked to 4 application scenarios so buyers can move from use case to matching products without losing context.

Keep Priority Business Loads Working Through Outages

Solar Backup for Shops, Clinics & Small Businesses

Design solar and battery backup around the equipment that protects revenue, stock, customer service and security. We size from your actual business hours, bills, outage pattern and equipment—not from a generic “small business” package.

Solar & Battery Power for Hospitality

Solar Power for Guesthouses, Lodges & Hotels

Design solar and battery storage around your room count, local grid, generator use and day-to-night load profile. Keep priority guest services available through outages while reducing generator hours and night-time noise.

Keep Teams, Networks and Customer Service Online

Solar Power for Offices & Businesses

Design solar and battery backup around the work that cannot stop: computers, networks, payment systems, communications, security and selected cooling. Use real operating hours and equipment demand to protect productivity through outages.

Build a Solar Range Your Customers Can Actually Use

Solar Products for Distributors & Installers

Plan a sellable product mix around the homes, shops, farms, hospitality sites and commercial projects in your market—not a container of disconnected components. We help match inverters, batteries, panels and balance-of-system products for quotation and stocking.

Overview

Reliable power when the grid cannot be relied on

20kw Split Phase Solar System 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 20kW

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.

Add pumps and comfort loads

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.

Send us the appliance and motor nameplates with your load list. We will check how much equipment can run together and allow for motor or compressor starting power.
