Before you order
- Size the inverter on the largest load you need to run at once, not on your monthly kWh.
- Check the battery is on the inverter’s compatibility list so they can communicate; we confirm this on every quote.
- Your panel strings must fall inside the inverter’s MPPT voltage window. Tell us the panels and we work out the string layout.
- Installation by a registered electrician with a Certificate of Compliance; grid-connected systems must also be registered with your municipality.
Delivered nationwide, with the delivery cost to your town shown at checkout before you pay. Covered by the manufacturer’s warranty, on top of your rights under the Consumer Protection Act. Prices include 15% VAT.
