Charge your batteries from the grid
What savvy solar owners are now doing is charging their storage batteries at night at the cheapest rate of electricity, this can make your bills 4 times cheaper without even using any surplus energy from your solar power. We work closely with companies such as Octopus Energy, Ecotricity, Utility Warehouse, Full Power and many more.
Monitor your battery storage system
All of our battery storage systems come with free and advanced online monitoring where you can see exactly how much your batteries are charging and discharging. On a live portal – our online monitoring also detects if there are ever any faults or problems and will send both us and you a signal (90% of faults within the battery portal can be resolved remotely.
Add extra storage at a later date
No need to worry about going too small at the time with your battery storage capacity, if your electricity consumption ever increases for any reason at all you can simply add to the capacity to give you an adequate amount of storage capacity.
You can also increase your system discharge rate by installing extra AC controllers in parallel.

FAQs
A battery storage system stores excess electricity generated by your solar panels (or other renewables) so you can use it later — typically at night or during cloudy periods — instead of exporting it to the grid or buying electricity.
Battery storage will not affect your Feed-in-Tariff payments as long as the battery is AC-coupled, which means that only surplus energy can enter the battery after it has clocked up on your solar generation meter.
- Deemed export: A fixed % of generated electricity is assumed to be exported — no export meter needed.
- Metered export: Smart meter tracks how much electricity you export to the grid
Yes, all of our battery storage systems are capable of charging from the grid overnight on an off peak tariff like economy seven or an EV tariff, this enables you to save up to 80% on your bill without even having solar.
Different energy providers are more suitable for each home. For example, Octopus Energy have great EV tariffs and Heat pump tariffs, whereas Utility Warehouse offer great economy seven tariffs where you don’t need to have an EV or a heat pump.
Yes, typically. You’ll use more of your own solar power, meaning:
- Less reliance on grid electricity
- Lower bills, especially if you’re on time-of-use tariffs like Economy 7 or Agile Octopus
Yes, all of our systems can be retrofitted to any solar PV system.
- The battery size should be matched to your generation and usage
- The Hanchu battery systems do not come standard with a backup feature. However, we highly recommend the Home Backup Gateway add-on. This critical feature allows for instant switchover during grid failure, ensuring essential circuits (like fridges, freezers, and Wi-Fi) remain powered, offering you true peace of mind and energy security.
