Talk Morgan Forums Community The Malvern Arms Is your PV solar array generating more

Here's a couple of graphs showing the benefit of having battery storage for your home solar array. The first is one of our systems yesterday, 4.8KW panels, 7 KWh battery, serving the higher demand side of the house. The red is power we've used from the grid, the green is power we've generated off the panels, and the blue is power we've used that we generated ourselves either direct from the panels or via the battery. The only gap we had was from 04:00 to 08:00 and those spikes in the middle of the night are the greenhouse heaters kicking in as it was a chilly night.



The second graph is from the other system which supplies the lower demand half of the house. Another 4.8KW array/7KWh battery and as you can see it covered practically all consumption apart from when we needed more than the battery and panels could provide as the battery has a maximum discharge rate of 3KW
