Battery storage can help you shift solar electricity into the evening and explore charging at lower-cost tariff periods.
During sunny periods your solar panels may generate more electricity than your home is using. A compatible battery can store some of that surplus for later use, reducing the amount of grid electricity you need to buy at those times.
Depending on the equipment and electricity tariff, some batteries can also charge overnight when import rates are lower. The economics depend on your usage, tariff and system settings.
MODEL YOUR ENERGY USE ↗Measured in kWh, capacity describes how much energy the battery can store. The right size depends on household consumption and likely available charging energy.
Measured in kW, this affects how quickly the battery can charge and how much household demand it can support at once.
Existing solar owners may need a compatible inverter or a separate AC-coupled storage solution. We assess the current system first.
Backup power is not automatic with every battery. It requires compatible equipment, a suitable electrical design and dedicated backup arrangements where offered.
We frequently specify Fox ESS hybrid inverters and compatible battery storage, including EP-series options, where they suit the project. Product selection is based on electrical compatibility, desired capacity, installation location and system design.
Whether you already have solar or are installing a complete new system, we can discuss the available upgrade routes.
DISCUSS BATTERY OPTIONS ↗Morning: Solar begins meeting daytime demand.
Midday: Surplus generation may charge the battery.
Evening: Stored energy may reduce grid imports.
Overnight: Depending on settings and tariff, off-peak charging may be possible.
Actual energy flow depends on weather, battery state, demand and configuration.
Yes, some battery systems can operate without solar and charge from the grid. Suitability and savings depend on the equipment, tariff and usage.
Not necessarily. Many standard grid-connected systems shut down during an outage. Backup requires a specifically designed and installed backup arrangement.
Some product families support expansion, subject to manufacturer limits and system compatibility.
No. An oversized battery may be underused. Sizing should reflect actual energy consumption and realistic charging opportunities.
