Eg4 6000xp solar and EPS issues

[Ellogar]

I installed the EG4 6000xp over the weekend, and currently am waiting for the proper battery to arrive, so I have the 6000xp set to no battery. I currently have the 6000xp going to a sub panel with a 2 pole 20A breaker running my Eg4 solar heat pump. I have 1 string of solar hooked up with 6 290w Trina solar panels each panel has VOC of 44.9v and ISC of 8.47A.

The heat pump runs fine in grid mode with eps bypass, but when in grid mode the MPPT only shows 1-3w coming in. When I open the grid breaker on the 6000xp and put it into off grid mode the solar will jump up to 72w input (it should be around 700w, I previously ran the solar directly into the heat pump and it worked great) but EPS remains in bypass. If I open the 2 pole 20A breaker in the sub panel while keeping the inverter in off grid mode the eps will finally show 17w going to the sub panel. Even when I lower the load from the heat pump to around 40w i get no results. Any insight would be greatly appreciated.

Any insight would be greatly appreciated.

waiting for the proper battery to arrive

That should solve your problems.
Make sure your firmware is up to date too.

Operating an off-grid system without batteries can cause some issues, as the system primarily relies on PV and battery for power. It is recommended to have at least 200Ah of battery capacity per inverter for optimal performance.

Ok, battery has arrived and is installed. PV input is still nowhere close to what it should be. It's noon and very sunny here, I should be getting 700w and it's still only taking in 50-70w. I have two different solar arrays that are 6 290w Trina solar panels each panel has VOC of 44.9v and ISC of 8.47A. I tried both arrays separate, same result. What's the issue here?

It is probably because you have chosen lithium battery and have not set up communication.

EG4 is petty dumb and there manuals are always a work in progress going from wtf to wtf were they thinking.

Communication is set up on the battery

I reset the inverter and got a much higher PV input

reset how?

 

[Ellogar]

reset how?

Through the monitor.eg4electronics.com portal. On the maintenance tab there's a reset option.
