Good evening everyone, I recently installed (myself) a completely off grid system here on my property. The system consists of:
40x blue sun 460W bifacial panels
2x EG4 18Kpv inverters in parallel
6x EG4 48v 14.4Kw power pro batteries
1x 600V EMP Sheild
1x15kw Diesel Generator
The issue I am having is power surges and dips. I am noticing a lot of flickering of my led lights in my house. Almost to the point I am getting headaches. I decided to put a DMM on the load terminals and found that when turning on a high draw appliance the voltage drops from 242v to about 226v and then stabilize back to about 240v fairly quickly. When the appliance is turned off the voltage will spike up to about 256v and then come down quickly. I feel as though this shouldn’t happen but I thought I would ask here before I go back to signature solar for support. They have been great thus far at troubleshooting but they seem to have limited knowledge with the new 18Kpv system. I appreciate an help or insight that can be offered.
Thanks,
Ps- The bare wires you can see in the LB are for a future grid tie connection. They are not currently connected to anything.
Edit to add a note about firmware. While working with signature solar support we updated to the newest firmware and the issues got worse. We then backdated to an older firmware and the issue seemed to go away or be almost gone for a while. I started noticing it again this evening
**Solved**
Turns out my Kureg was causing the problem. Apparently it maintains hot water. It was causing the lights to flicker every 30-45 seconds.
