About How big a wire should a 50kw photovoltaic inverter use
Commercial solar PV panels over 50 watts or so use 10 gauge (AWG) wires. This allows up to 30 amps of current to flow from a single panel.

4-core 16mm2 SWA cable is not really suitable for 50kW system because it's rated at 75A. As long as your current is about 80A, I would recommend 25mm2 (rated at 96A) keeping the losses about 2.6% or even better 35mm2 (rated at 115A). The selection of the cable is also based on the MCBs that you gonna use.

6 FAQs about [How big a wire should a 50kw photovoltaic inverter use]
What is an inverter wire size calculator?
» Electrical » Inverter Wire Size Calculator Online An Inverter Wire Size Calculator is a specialized tool designed to help you determine the optimal wire size needed for your inverter setup. This calculation is crucial for maintaining the efficiency of your electrical system and preventing potential hazards like overheating wires.
What size wire do I need for a 2000 watt inverter?
For a 2000 Watt 12 Vdc inverter, we always recommend at least 1/0 AWG cable. The cable size is determined by the inverter's max running wattage.
How much current do I need for a 24V 3000W inverter?
EXAMPLE: For a decent 24V 3000W inverter with 90% efficiency we calculated 175A as the max continuous current. If our round trip is 40ft, the online calculator tells us we need 1/0AWG 90oC wire The following chart is for 12V nominal systems, and the ‘Circuit Length’ is the round-trip length from the battery to the inverter and back.
What is the minimum fuse size for an inverter?
Fuse Size = 138.9A x 1.25 = 173.6A (This is the minimum fuse size for the inverter. This should be rounded up to the next standard fuse size. In this case it might be 175A Step 4: Look up the wire size need to handle the fuse current. Use the table on page 3 to look up the minimum safe wire size needed.
How much cable do I need for a solar inverter?
We recommend 4 AWG cable for our 3000 Watt 24 volt inverters. For our 60 amp solar charge controller to battery bank, we recommend 6 AWG cable. Thank you in advance. I currently have the following batteries and inverter.
How do I know if my inverter cable is efficient?
The efficiency rating, or cable efficiency, is typically provided by the cable manufacturer. You can find this information on the cable’s packaging or the manufacturer’s website. An Inverter Wire Size Calculator is a specialized tool designed to help you determine the optimal wire size needed for your inverter setup.
