Hi All,
We have an "off grid" setup which is proving to be costly on our electric bill due to early morning charging from grid. I am reaching out to the community for advice on how reduce / prevent this charge spike and hopefully reduce our bill (please refer to charts below).
Installation:
2x Growatt SPF 5KW, 4x Pylontec 3000C Li batteries, and solar panels to product 5KW, Solar Assistant monitoring system.
Issue:
Currently, the average load throughout the night is approx. 800w. The batteries are able to service this load until the batteries reach 20% (47.6V) - around 4:30am. This is when the grid is used to recharge batteries to 80% (51.0V). This charging period lasts around 2.5hrs and at a rate of 35.A which registers the 4Kw spike in the graph below.
Does anyone have any suggestions to either reduce this spoke or even prevent it (e.g. firmware upgrade, inverter settings), or do we need to add additional batteries?
Any help will be greatly appreciated
