Add storage to existing solar
Your panels may stay in place, but the inverter and electrical setup determine how storage can be connected. Have the inverter’s model and your solar system details ready so we can assess the equipment you already own.
Use more of your solar electricity after the sun goes down. We’ll check your existing system, evening electricity use and backup priorities before proposing a battery for your Essendon home.


These opening images show SEN installations. See Essendon job photos below.
The Essendon job photo below shows battery cabinets beside a brick wall. It is one installation layout, not a placement rule for another property. At your address, the proposed position needs its own check.
Battery installation rules include restrictions on wall materials and distances from doors, windows and living spaces. Think about access to the proposed wall and nearby openings when discussing a location. A clear-looking wall or garage does not by itself establish that a battery can go there.
Read the Australian Government’s battery safety and installation guidance.

The SEN person who assesses your home also designs the system. Our in-house team installs it, with a local base in Tullamarine.
These two cabinets and wall-mounted equipment are from the Essendon solar and battery job on our overview page. They show real local work, without implying that your home needs two cabinets or the same arrangement.

A call about your home. Tell us what you have now and what you want solar or a battery to do.
A proposal you can review. We put the proposed system and price in writing, so you can see what is included.
A site visit before a firm price. If you want to continue, we check the installation details at your property and put any changes in writing.
Possibly. Keeping panels and adding storage depends on the existing equipment and the proposed connection. We check the panels and inverter before recommending a retrofit, so a battery quote does not assume the whole system must be replaced.
Only if the system is designed to do that within its limits. Many backup arrangements supply selected circuits. The equipment, circuit selection, stored energy and output determine what works during an outage; ask for those details in the proposal.
Start with your electricity use after daylight and any backup priorities. Compare usable stored energy and power output separately, then consider how much electricity is available to charge the battery. A neighbour’s battery size does not establish the right size for your home.
That needs a comparison using your usage, electricity prices, installation cost and equipment life. Ask which assumptions sit behind an estimate and how it changes if your tariff or routine changes. Solar Victoria’s battery guide explains the costs and benefits.
Check the Clean Energy Regulator’s current battery programme rules. The proposed equipment and installation must meet the applicable requirements. A discount or eligibility should not be assumed from the battery size alone.
Tell us about the solar you have, the power you use after daylight and the appliances you want backed up. We’ll use your free assessment to work through the storage options and next steps.
