I have 2 strings of 6 panels each (Longi LR5; no optimizers or micro-inverters.) One string is in full sun while the other gets partial shade in the morning due to my neighbor's tree. When all are in full sunlight, each string produces about 3kW. However, when that one string is partially...

My Gobel DIY battery box kit arrived with an EK-24S4EB 'Flying Super Capacitors Balancing' board even though I did not order a balancer. Of course, there are no instructions, and I cannot find much information about it. It does seem to have Bluetooth capability. The16 MB30 cells for the box...

I have a Gobel 48v DIY battery (~305Ah) and will soon be adding an additional identical one in parallel. Both already have a beefy 250A circuit breaker and a 200A Pace BMS, but no fuses. Typical maximum draw will be 100A (both in and out.) Do I really need to add two class T fuses to this...

I have my Gobel DIY battery box with MB30 cells (304Ah) supplying my 18Kpv inverter. All is working flawlessly but I want to double my storage capacity as the battery pretty much drains each night now that winter is approaching. I have ordered a duplicate battery box, but with MB31 cells...

I have my 18Kpv set to charge the battery just after midnight to take advantage of the cheaper rates. Charge is limited to 50A and it usually takes about 3-4 hours to regain a full charge. Today I noticed that the 50A charge rate only worked for awhile then went into standby, came back on...

I have 12 panels that are ground-mounted about 200 ft from my electrical panel. I did NOT run a ground wire to the panels...instead, I sunk two 8-ft ground rods next to the panels, about 15 ft apart. I should note that I am in Northern California where we almost never get lightning. Anyhow, I...

I have noticed that an LED bulb in my lamp continuously flickers very slightly when the 18Kpv is running on battery. I am not sure if it does the same when running on solar (because I don't have the lights on during the day), but I will do more testing. After some research, I replaced the...

I am new to solar and am beginning a mostly DIY installation of a system based on the EG4 18Kpv (no micro-inverters.) I am planning on about 15kW of battery backup. I am a retired electrical engineer, but do not know much about power systems. I am in California and will have to deal with...

When I access my 18Kpv via the EG4 Monitor program and select Configuration, then Devices, the 'BattCapacity' is listed as 50AH which I assume is a default value. I also see this on the unit's built-in display and the mobile app. However, my battery is 305AH and I can find no way to change...
