A battery stores solar energy for later and keeps selected loads going when the grid drops. Capacity matters, but usable energy, the load you put on it, compatible inverter hardware and the warranty matter just as much.
SolarGuide compares options and refers enquiries. Alumo confirms the final system design, supply, installation, finance and warranties.

See full specsWhat to check before you compare quotes
A useful solar quote connects the component list to the home it will serve. Ask for these decisions in writing.
Compare usable energy, not only the label
A battery’s kWh rating is a starting point. Usable depth of discharge and your actual load determine the backup time you experience.
Start with the essential circuits
Lights, Wi-Fi, a fridge and charging are very different from an oven, geyser or air conditioner. List what must stay on first.
Plan for expansion honestly
Some systems can add matching battery modules later. The quote should state the compatible model and the practical expansion limit.
Common questions
How long will a solar battery last during load-shedding?
Runtime depends on usable battery capacity and the appliances drawing power. A small essentials load can last many hours; heavier heating appliances can reduce runtime quickly.
What battery chemistry is used in home solar?
The listed SolarGuide home batteries use lithium iron phosphate (LiFePO4), a common chemistry for residential energy storage. Check the exact manufacturer warranty and operating conditions for the selected model.
Can a battery work without solar panels?
Yes. A battery-and-inverter system can provide backup from grid-charged storage. Panels add daytime generation and can reduce grid electricity use when the system is properly sized.
