RE: 18kPV 1/3000 CTs installed "correctly" grid consumption underreported by 60% compared to utility company meter

Title says it all. How accurate can I expect the inverter's notion of my grid consumption to be compared to the utility company? Whole house configuration with feeder tap - i.e., no other circuits before the CTs in the incoming feed. I've validated direction and L1 vs L2 etc. Based on nother post, its very obvious when the Ls are reversed!

CT Power Offset in maintenance tab may be what you are looking for.

RE: EG4 14.3kWh indoor wall mount battery BMS comms issues - resulting in blackouts, power blips, and charging restarts

Deep power cycling the battery, BMS and Inverter did not solve the 'blip' issue.

Switched back to Lead Acid mode for a time being. Will try to update the battery firmware and power cycle again sometimes in the future.

MPPT Production Change

Johnaand — Mon, 01 Jun 2026 23:25:39 +0000

I have a Flexboss21 Inverter with 28 solar panels connected to MPPT's 1,2 & 3. Up until today I have been getting great solar generation from all three MPPT's. I have attached the Ppv1,2 & 3 charts for yesterday (5/31) and today (6/1) and there is a definite change to MPPT's 1 & 2 that started about 9:38AM today. As you can see MPPT-3 does not appear to be affected. Looking for any help on what is going on.

Thanks,

12000xp Ham Radio Noise

radioman — Mon, 01 Jun 2026 21:46:30 +0000

Hello,

i was wondering if anyone has any experience with this unit and HF radio noise being generated from the switching transistors, my location is very quiet for HF noise and i don't want to introduce it,

should i stick with a low frequency device? does anyone use this unit with ham radio equipment ?

Thanks

Anthony.

Any idea what this firmware update even does?

Firmware update Issue - SOLVED.

I have disconnected the system from the grid and PV array. Deep power cycled all components for over 30 min.

Then logged out from my EG4 monitor on my phone and downloaded the most recent firmware for 6000xp to the phone.

Disabled all wi-fi connections on the phone - connected to inverter's WiFI Dongle and forced firmware upgrade.

The whole process too 15-20 min. Then power cycled the system again and..... ALL works again.

Hope that might help if firmware reload is needed.

@ EG4 Eric - pls disregard my previous firmware downgrade request - let's see if the latest one holds
