You were all correct in assuming i'm an idiot. I was indeed using the lead that also connect to the clamp meter to do just that as I was unsure if it could be done with the clamp meter.
All of these conditions were met, and seem to happen frequently. In their positioning, each panel is...
Just got off the phone with two different electricians and they both had completely different opinions on what to do. Each thought the other was a donkey.
In planning my system I though that driving an 8' ground rod into the earth and attaching a bare copper wire to the main panel would close...
The run from the inverter to the panel is 5' 2" of 6-3. Is the length important because a longer one presents more opportunities for current to leave that loop? Just like grounding, the ground neutral thing gives me 10 questions for every 1 I think I answer.

After the update you'll get the display to update when connected to EG4 batteries. You'll also get a new error code 69 which is not documented anywhere but means the batteries are full. (when they are full)
Ah ha! So this 20+ number is just gibberish or maybe some kind of interference? This would make sense as to why my other readings, including with the clamp are accurate.
The plans it to put 6 445w Solarever Panels in each string then use branch connectors to parallel those 2 strings. Running a single pair to the controller. The charge controller can do 5000w / 500v and the panels are 49.86V.
Where can I learn more about floating pv mains? I'm trying to understand this and that might be a huge mistake because it seems, concerning grounding, the more I learn, the less I know.
In this illustration the PV frame grounding connects behind the grounding for the inverter/expensive stuff. In all i'm learning about grounding, it is always stressed that the ground connection occur in one place. How would this physically look as a mechanism? If you've got a rod, with a wire on...
I understand that the SCC will negotiate how much amperage is pulled from the string. In my case, I have an 80A SCC with a max 18A pv input. (EG4 3000EHV)
When I connect a single string of 6 panels I can watch the amperage change. But the rating on my panels is 445w and I watched 6 of them put...
I have an EGC, and I definitely have a N-G bond. What i'm concerned about is that the N-G is being bonded in two places and what symptoms that might present for me to determine if this is the case.
So I should likely just fuse at slightly over what the SCC says is the max on amperage. The EG4 3000EHV says it has a max current draw input of 18A, so 20A inline fuse should protect it from damaging over current, correct?
Hm. I'm very curious about this signal noise. Is this audible? Our system performs normally with a single oddity. When running a very specific load - a hair dryer on medium (not low or high), the inverter, which has a transformer (6000ex), gets very loud. It sounds like it is resonating. No...
I think this makes sense. I should have clarified that there is no AC input. It is a metal box on concrete pillars. Nothing inside or anywhere near it. Considering that, would a ground rod act as the most effective form of protective earth system?
Not sure if this his helpful or not but i'm experiencing the same/similar problem. What I noticed is that the EG4 setting for battery type using the BMS communication cable causes the display screen to hang and not update. I removed the communication cable and set up user settings for the...
I received the same response. It appears the GNB occurs internally when inverting from the battery. So I would assume that because I have my neutrals and grounds on the same bus and I only invert from battery as I don't have an AC IN that I do have a double GNB. But i'm still not sure if that's...
I don't have a sub panel. The one pictured here is my main panel. It goes inverter > panel > outlets. Does that still apply? Part of my confusion stems from the fact that these little panels are sometimes used as sub panels in my area as well.
I took the positive from one end of the string and the negative of the other end ( 6 445w panels ) and used the meter probes on dc voltage. Then pulled them out of the mc4 connectors, switched it to DC amps and did the same thing.
Are you saying that the probes will not read amps or that I...
I've got a 6S2P array with 12 445w Panels. The panels have an ISC of over 10a and a maximum series fuse of 20a. I've seen several people on this forum say you don't need an inline fuse with 2P but i'm not sure why.
Why would 2P not require an inline fuse? Does it have something to do with the...
I have 12 445w Solarever Panels mounted to a metal roof with s4 "screw in" brackets. They charge an off grid battery bank with an EG4 6k inverter/charger. When the disconnect is open and the batteries are charging I feel a slight buzz in the painted metal roof. ( when touching the bottom side )...
I've got the fans humming pretty loud. The thing sounds like a jet engine when 5kw solar input is reached as well. But this other sound from the very particular load is something else. Deep and resonant, not sure if it's normal as i've never had an inverter with a big ol transformer in it before.
When running a hair dryer my inverter makes this crazy resonating sound. It only happens with the hair dryer and it only happens when the hair dryer is on the low setting. No other loads i've tested, regardless of wattage, cause the inverter to make this sound. The inverter has a transformer...
Anyone foresee any issues with me replacing the existing plug on the Chargeverter with one of these:
Then just plugging it into the inverter with an extension cord?
I've got a Honda 2200i that has a running wattage of 1800.
I'm thinking that way I can't ever forget that it's only 120 and if...
