Hi DIYSolar Family, Appreciate help on what is causing two of ten 48V EG4 LifePower4 batteries have lower states of charge, see image attached. I am using the master cable and mode USE for all EG4 inverters. All batteries have their Ethernet comms cable and dip switches are all different. I...

Hello DIYSolar Family! I appreciate help with isolation of a low voltage PV string. From the 7 strings of panels, I am reading 260 volts at the MC4 connector, but at the fuse box 100’ away, I am reading 38V and -2 amps using noncontact ammeter on positive wire. Any ideas on how to isolate this...

Hello DIYSolar Family! As a farm, we rely on accurate weather forecasts and with our location we were getting up to 10 degrees F swings. Using analog and mechanical systems has also not led to reliable results. I purchased a Tempest WeatherFlow weather station and installed two days ago and...

After seeing folks struggle with how to connect battery racks to busbars (buss bars) and circuit breakers, I share my Battery interconnect combiner design to give ideas to future built systems. Many use the puny busbars and then have exposed wiring and exposed circuit breakers. This single box...

Hi All! During the bitter cold last week, our Mr Cool DC inverter universal 4/5 ton heat pump was running through the night. In the morning, wife noticed house temperature was decreasing but air handler was running. I discovered condenser/ compressor CB had tripped. I reset the 50 amp breaker...

After installing 60 panels and commissioning our EG4 6500EX 6 inverter system, I realized we had far too much tree shade. After trimming two large oaks, the system is now generating over 2kW at 9am and has solid production throughout the day on all panels. In Florida, I learned that the high...

Hello Solar Aficionados! Appreciate sharing thoughts on bypass modes, what typically triggers them and out to exit out of them when inverters seem stuck in that mode. I noticed this morning that my system defaulted to bypass mode sometime since last night. When I last checked at 6pm last night...

Hi All- Appreciate help with an anomaly observed during testing today. I am seeing irregular readings from my PV array at the inverters. My mm shows 245V, measured at Disconnect, but inverter shows 81V, 0.2A and and only 19W. I had two parallel streams, but separated them after SS tech said...

Many thanks goes out to this forum. While I have only been active on here for a few weeks, I get the sense of very kind and thoughtful people who like helping others navigate the mysteries of Solar Power Generation. I came here because no where else had answers, but within a few weeks, my...

All- I reposted this as separate topic to focus on common neutral used across two split phase inverters. Appreciate the community experts help on my EG4 6400 6 Inverter Installation. My inverters are wired to Grid Input, PV array, and EG4 batteries. I used a three wire 4 Ga with ground to...

All- I have read a lot of confusion on how the EG4’s switch the neutral depending on AC pass through, battery charging, etc. Note that my only Neutral-Earth-Ground bond occurs in my first means of disconnect from the power line meter. So appreciate final thoughts on the Neutral-Earth-Ground NEG...
