Don't need to connect Load output port with Sol-Ark 15K Inverter?

freethink · May 6, 2024

Hello everyone, I’m setting up a solar system and thinking about getting a Sol-Ark 15K inverter, but I don't have any batteries.

I don't need to connect the Load output port back to the main panel, is that correct? (Since I don't have any batteries to run any backups).

Thank you and looking forward to your insights!

I think the Sol-ark can use the solar panels to run you load center if the grid tie power is off. Are you grid tied or off grid? Someone that knows more can chime in here.

I can't say, as my service is connected directly to my inverter with a disconnect in between. So, my main panel is connected to the load output.
Personally, if that's an option, it seems to me to be the easiest way to do it. In that setup, I did run with PV and no battery for about a month.

If you are talking about connecting both, the grid input and load output to the same panel.
Absolutely not.

If you are just planning on having PV panels and selling to the utility you only need to use the GRID terminals to do so.

The LOAD terminals are for if you have batteries. Any loads you would want the inverter to keep alive during a grid outage would go on the LOAD terminals. However, if you don't have batteries you don't need to use them at all.

Because the Sol-Ark 15K has a 200Amp passthrough some people still put their whole house on the load terminals. The meter lines would then go straight to the GRID terminals and the expectation would be that in the future they will get batteries to back up their whole house. This prevents them from having to rewire anything when the batteries are added. If you do this I recommend having a bypass switch so that you can bypass the inverter and supply your main service panel directly from the utility in case the Sol-Ark needs to be serviced or experiences a failure of some sort.

That's very helpful. Thank you.

If I can do it, you can do it.
