"Limit inverter power"
Hello, I have a pair of 240V MultiPlus-II 5kW units connected in parallel and operating effectively to a grid set-point of 50W; charging when there''s excess PV and
Please refer to the manual for the charge and discharge limit of your inverter. When selecting the charge and discharge current limits you will always be limited to the lowest current value whether that is the inverter or the batteries. For example, the 3.6kW Ecco inverter has a 90A maximum charge/discharge current.
What is the Maximum charge current from grid inverter to battery with a MultiPlus II 5Kva. We have 10Kw of lithium, 6.6Kwp solar connected to a fronius 5Kw grid inverter on AC out of a MultiPlus IIGX for offgrid use. We often see the fronius being ramped down and don't know why. The maximum charge current is about 50A, which is about 3200W.
If batteries are in a parallel connection, the inverter charger must supply the current needed by every battery. So if the battery current limit is 20 amps, and there are two batteries in parallel, the inverter must provide 40 amps (20A x 2 batteries).
You can use a 12V rated inverter charger to power it. The maximum capacity is 600ah, similar to the series. The difference is the voltage because in a series connection it goes up to 36V. If batteries are in a parallel connection, the inverter charger must supply the current needed by every battery.
For example, the 3.6kW Ecco inverter has a 90A maximum charge/discharge current. Two 5.12/5.32kWh batteries have a continuous discharge of 100A. This means that the maximum charge/discharge is limited to the 90A of the inverter.
One battery charging or discharging at 50A will discharge at 58.4V x 50A = 2.92kWh. The charge and discharge current in the inverter settings is the total charge and discharge current of all of the batteries connected so 2 batteries would be able to charge or discharge at 100A, 3 batteries at 150A, etc.
