Maximum amps on Back up/load side 16kw Max
Good afternoon, could somebody please help me in regards to the maximum load that can be wired into the "load/back up" terminal on this inverter?
With other manufacturers it has been reccommended that you limit the amount you wire onto the back up side to the maximum discharge rate of the batteries therefore in worst case conditions ie nighttime in a power cut the draw of the back up circuits won`t be more than what the batteries will discharge at. This protects the inverter from tripping. For the 16kw Max inverter is this also the reccommended method? I can see the diagram on the manual which says to place an AC breaker but I wanted to check other whether sizing the breaker to match the battery discharge is the correct method and there isn`t a better way for this inverter? The client I have want`s to have whole home back up but I can`t see that this would be possible with this inverter? Many thanks for any help in advance.
4 * 5.12kWh batteries is a total of 20.5kWh.
The total discharge of 4 batteries in parallel is 4 * 50A = 200A
This would be able to supply a max load of approx 10kW for one hour (or a load of about 40A for the 230V side). You can discharge at a slightly higher current for a short period of time if you have some peak loads.
