Desired backup hours
Usable capacity, not just Ah
Battery–inverter compatibility
Operating and warranty conditions
Nominal capacity is only the beginning
A battery’s labelled capacity is not always the energy you can use. Permitted depth of discharge, inverter efficiency, temperature, ageing and operating limits all affect useful backup.
Compare batteries on the same basis
Compare chemistry, nominal voltage, usable kWh, charging limits and warranty conditions. Amp-hours alone are not a fair comparison between different voltage systems.
Design for the actual environment
Location, temperature, ventilation and manufacturer guidance matter. Equipment should be protected from inappropriate heat, water and unauthorised access.
Read the warranty conditions
A long warranty label does not explain all of the cover. Request the operating conditions, exclusions, claim process and any maintenance or registration requirements in writing.
Questions before you begin
How much does a solar system cost in Aba?
The price depends on your appliance loads, backup hours, battery capacity, equipment and installation requirements. An itemised proposal is more useful than a price based on inverter kVA alone. Our cost guide explains what to compare.
Can solar power my freezer or air conditioner?
It can be designed for those loads, but running watts, compressor starting demand, operating hours and battery storage all matter. Share the actual appliance ratings for an assessment rather than relying on a generic package.
