Sungrow / Battery storage
CommercialSungrow PowerKeeper commercial battery
Sungrow's modular commercial and industrial battery from 49.9 kWh to 249.6 kWh, built from 12.48 kWh packs.
Needs a hybrid inverterThis is the battery only. It stores solar and runs your home through a compatible hybrid inverter. If you already have a standard solar inverter, we would look at a different setup.

WHY THIS BATTERY
49.9 to 249.6 kWh, same battery underneath.
Every size in this family uses the same modules, the same chemistry and the same warranty. Adding modules adds storage and, on this design, adds power with it. What changes is how long it runs and how much it can run at once.
Key specification
- Model codeThe code on the unit and on your proposal
- Usable capacityWhat you can actually draw, not the nameplate
- Power at onceHow much of the house can run off it simultaneously
- SurgeWhat it can start — motors draw far more than they run on
- Energy through the warrantyTotal energy guaranteed over the term, whichever comes first
- WeightDecides whether the wall or the floor carries it
Cell detail, voltage windows, fault currents and the full standards list are on the manufacturer datasheet.
How long will it actually run my house?
Divide the usable capacity by what your home is drawing. Most households sit around 0.3 to 0.8 kW overnight and spike to 3 to 6 kW in the evening with the oven, kettle and aircon. So a battery of this size covers an ordinary evening and overnight comfortably, and far less if you are running heavy loads. We size it against your actual bill rather than an average.
Will it keep my house running in a blackout?
Only if backup is specified and wired. A battery on its own does not do it. You need an inverter with a backup output, the backup circuits wired to a separate sub-board, and on some products an extra gateway. Most homes end up backing up essential circuits — fridge, lights, internet, a few power points — rather than the whole house, because the oven and ducted aircon alone can exceed what any home battery delivers.
What is the difference between usable and nameplate capacity?
Nameplate is the energy in the cells. Usable is what the battery management system will let you take out. The usable figure is the honest one and it is what the federal discount is calculated on, so it is the number shown above.
How does the federal battery discount work?
The Cheaper Home Batteries Program is delivered as certificates your installer creates and takes off the invoice up front, so you do not claim anything yourself. It is worth about $265 per usable kilowatt hour at the current rate, and it tapers: the first 14 kWh gets the full rate, 14 to 28 kWh gets 60% of it, and 28 to 50 kWh gets 15%. The rate also steps down over time, so the figure on this page is today’s.
Where can a battery actually be installed?
This is set by the wiring standard, not preference. Batteries cannot go in habitable rooms, ceiling or wall cavities, under stairs or on an escape route, and they need clearance from windows, doors and vents. A garage that is not used as living space, or an external wall out of the afternoon sun, is usually where they end up. We confirm the position on site before quoting.
Should I get a bigger one while the discount is high?
Only up to a point. The discount pays the full rate on the first 14 kWh and only 60% on the next band, so the value per kilowatt hour drops as you go bigger. Past a certain size you are paying close to full price for storage you may only use a few times a year. The right size is the one that gets you through your own evening, not the largest one the rebate touches.

BACKED BY US, NOT JUST THE MANUFACTURER
A 10-year workmanship warranty on solar and battery installations.
Manufacturers cover their products. We cover the installation. For 10 years from practical completion, a defect that comes from our workmanship in installing your solar panels, inverter or battery — the mounting, the cabling, the installation work — is put right by us: repaired, re-done, or the affected installation part replaced, at our cost and at our choice of remedy.
- It stays with the home. Sell up, and the new owner gets the remainder, on the same terms.
- Switchboard, EV charger and heat pump installation work carries its own 1-year workmanship warranty from the date of installation.
- It covers our work, not the products. A panel, inverter or battery fault is a manufacturer warranty matter, with its own period.
- What it does not cover: damage from misuse, changes or repairs by someone else, storms, surges and grid events, pests and corrosion, building movement, ordinary wear, and internet or monitoring problems. A call-out where no workmanship fault is found may be charged.
- Keep your rights. It adds to the Australian Consumer Law guarantees, never replaces them.
- To claim: email engineering@solar4life.com.au or call 1300 997 005 with your name, the installation address, what is wrong and photos. Tell us promptly; delay can affect a claim.
Residential installations. The full terms are in your installation agreement.
