FAQS 4
How does my inverter deal with ground?
How does your inverter deal with ground. Folks, When setting up an inverter, one of the more important safety things to get correct is the grounding and the neutral-Ground bond. All of the inverters have a ground connection on the AC out. Some inverters have an AC in and when they do they have a ground connection on the input.
Do all inverters have a ground connection?
All of the inverters have a ground connection on the AC out. Some inverters have an AC in and when they do they have a ground connection on the input. Sadly, the information provided in many manuals is nearly non-existent when it comes to how it handles ground internally. Are the two (or three) grounds tied together? Is there a neutral-ground bond?
What happens if the DC cable connects to the inverter?
3) The insulation layer of the DC cable connecting the string to the inverter is damaged and connected to the ground. Troubleshooting: Disconnect the DC switch of each PV string connected to the inverter, and use a multi-meter to measure the voltage of the PV+ to ground and PV- to ground of each string.
How many watts is a 2000 watt inverter putting out?
However, if the inverter is putting out 2000 W, the input current will probably be over 200 A at 12V. I would like to read the inverter installation instructions, but probably you need to ground the battery to chassis near the battery (DC ground) and ground the inverter to the chassis near the inverter (AC protective earth ground).
