Affordable? Absolutely.
Dependable? Without a doubt.
A top-tier product? Absolutely, yes.
Your inverter is the computer that tracks and monitors everything
It’ll keep talking to the grid, your battery, your software, any solar you have, and all those various bits and pieces.
It’ll also convert energy so that it’s good for use in your home. (From DC to AC, to be specific.)
If your battery is the heart pumping out energy, your inverter is the brain that keeps everything working just right.
A solar inverter and a battery inverter in one tidy little unit
Two power capacity options, to meet your power needsSeriously high cost-performance ratio (aka, bang for that buck)Can be installed nice and neat in a standard server rackLoads of inbuilt safety featuresSupports voltage balancing function during charging (or passive balancing for the techies)Supports multiple parallel operations, so you can scale as you likeDisplays key info like charging/discharging voltage and current via a handy digital screenHarness up to 9kW of useful generation DC/DC charging from solar for maximum efficiency
5400W max. DC power

It's robust, offers exceptional value, and prioritizes safety above all else.
If you’ve got solar panels in place, you can charge it for free and save the sun’s energy for later.
If you’ve not got solar panels, use smart tariffs. On a smart tariff, your battery charges when energy is cheaper than normal. (Like overnight, or when wind farms are giving the grid loads of power.)Either way, that lovely cheap energy in your battery will supply your home when you need it. Bingo – you’ve just dodged peak rates.
