Solar Power Storage Batteries

Batteries give you energy independence

Whether you're connected to the grid or not, store your surplus solar energy to keep your lights on during grid blackouts or when the sun isn't shining. A large portion of our electricity usage is at night - just think of the heater in winter or the airconditioner in summer! Then there are the appliances that run 24/7 such as fridge, freezer, pool or spa. Adding a battery to your home enables you to use more of what you produce, saving you on your electricity bill and reducing reliance on fossil fuels.

Choose a hybrid inverter to future-proof your system

Batteries are a long-term investment, and maybe you're not quite ready. You can keep your options open by installing a hybrid inverter that's ready to have batteries connected in the future, or choose a modular option, such as Redback Technologies, Sonnen or Alpha-ESS, that allows you to start with a small battery of even 2.4kWh with the option to expand your storage down the track.

Do you experience prolonged black-outs?

When the grid goes down, you may think that having a solar storage battery will save you from the inconvenience of losing power. This is true - up to a point.

In the instance of a black out, your system will continue to operate as usual, until you totally deplete your storage battery. At that point, your system will stop functioning - you won't even be able to use electricity directly from your solar panels while it's being generated during the day. This is a technical issue where the system requires external power (from the grid) to restart after the battery has been completely drained and shut down.

"Black Start" is a functionality that eliminates this problem.

Having Black Start capability means that your system can restart itself after being completely drained, while the grid is still down. If you drain the battery overnight, for instance, as soon as the sun rises again, you will be generating and using your solar power (and storing any excess!) as usual.

Two of the brands we recommend - Redback Technologies and Sonnen - both provide Black Start functionality and are the options we recommend for those who experience prolonged blackouts.

Tesla Powerwall 2
with Gateway

A Powerwall system consists of at least one Powerwall battery and a Backup Gateway.

The Backup Gateway provides energy management, metering and monitoring functions for Powerwall. It controls connection to the grid, safely disconnecting your home and starting backup operation during an outage. The Backup Gateway also includes communication functions for up to 10 Powerwall units, and receives over-the-air updates for the system.

Powerwall is a rechargeable home battery system that stores energy from solar or from the grid and makes it available on demand. It can power your home during the night, or back up your home in the event of a power outage. With its built-in battery inverter, Powerwall is compact and easy to integrate into your home.

Grow Energy is certified to sell the Powerwall 2 with Gateway. Give us a call to talk specifics.
