Home battery storage
Use more of your solar after sunset.
A battery can store surplus solar for later use. The right starting point is how much energy your home produces, when you use it and what you want the system to do.
01
Existing solar needs an individual check
Having solar panels does not establish that a battery can connect directly to your current inverter. The model, electrical phase, age, available connections and manufacturer compatibility requirements matter.
Share a photo of the inverter label when requested, along with any system documentation. Sunlands Solar will assess whether an appropriate battery upgrade or a different system arrangement should be considered.
02
Capacity and power answer different questions
Battery capacity, usually expressed in kWh, describes stored energy. Power, expressed in kW, describes how quickly the system can supply or receive energy. Usable capacity and the operating settings also matter.
Review evening demand and available daytime surplus before selecting a size. A larger battery may not be well used if the home cannot regularly charge it or use the stored energy. Future demand should be considered explicitly.
03
Backup requires a deliberate design
A battery does not automatically keep the whole house operating during a blackout. The inverter, backup capability, electrical wiring, selected circuits and load limits determine what can operate.
List the appliances you would like supported and distinguish essential circuits from large loads. Ask for the proposed backup scope and limitations in the quote.
04
Judge savings using your own tariff and usage
Potential savings depend on the electricity replaced, feed-in tariff forgone, charging/discharging losses, operating choices and installed cost. Time-of-use or other tariff arrangements can change the result.
Ask for the assumptions behind any savings estimate and compare relevant warranty terms and exclusions. We do not promise a fixed saving, payback period, rebate or universal compatibility from an initial enquiry.
