Had a whole house EPS set up installed with a manual switchover. Thought i'd give a bit of test as it was a lovely day and plenty of solar. Ran from about 17:40 - 18:55. But looking at the power levels it appears that the load power was higher than that being provided by the inverter (EPS), and no evidence of battery topping it up. And the EPS voltage was down. Is this normal EPS behaviour ?
