A quick post. I was looking at the prices to install a home battery system the other day. During the sales process I was informed that for a modular system such as the one provided by Ampetus that if you don’t buy 2 or more batteries that
“you may de rate system capacity”
Sound’s impressively scary! Slightly worried I asked that it means. Thankfully what it actually means is that instead of getting 3kW delivery using two batteries that one battery matched with the inverter may only deliver 1.5kW. This is not a problem if you are still connected to the grid but it can mean that your inverter isn’t working at its full potential. So in short nothing to worry about.
