Home Use max Current?


Jaco De Jongh

Question

From your own setup.

1. What is your max AC demand (A) on your inverter circuit.

2. What is the max AC demand (A) at your grid connection.

3. What is the max DC demand from the batterys

4. What is the max charging current you allow from each inverter. 

5. What is your total amps on your PV side. 

6. If you feed back to grid, What is the max (A or Watts) you export. 

I am trying to get info for a little project i am busy with and need some figures to play with.

20A, maybe 25A.

In winter we sometimes (though very rarely) overload it in the evenings, so 60A.

100A (but that is at 24V).

LFP, so I allow the full capability of the charger: 70A.

Around 70A after the MPPTs, at 24V (or more like 26V most of the time). More like 30A before the MPPTs.

I don't export.

1. What is your max AC demand (A) on your inverter circuit. - 36 amps/2 (18 amps per inverter)

2. What is the max AC demand (A) at your grid connection. - seldom exceeds 50 amps (in Winter)

3. What is the max DC demand from the batterys - never exceeds 166amps (4kW per inverter)

4. What is the max charging current you allow from each inverter. - 40amps each (80a total)

5. What is your total amps on your PV side. - 40amps per inverter (midday spring)

6. If you feed back to grid, What is the max (A or Watts) you export. - I don't

October kWh - total consumption 909 / Grid consumption 143 / PV production 882
