    EG4 6500 car charging problems

    Finally got the problem fixed by replacing the inverters with the 6000xp inverters. One of the 6500ex inverters shorted out and flipped my main breaker and several of my battery breakers. It damaged 2 of the battery bms boards and signature solar sent me new ones to get them back running again...

    EG4 6500 car charging problems

    I called them about it some time back and they wanted me to jump through hoops to get started with finding out what the problem was. I have delt with them on another inverter that just had a simple communication board go bad and almost 6 months later and countless emails and phone calls I got...

    EG4 6500 car charging problems

    I am currently running 79.70 with screws removed and bonding in panel. I wasn't aware the inverter would switch modes when the sun went behind a cloud.

    EG4 6500 car charging problems

    I have tried both split phase and single phase and get the same problem. I am really surprised they keep selling these when they have major problems. I could do the upgrade they are offering but if they are currently still selling these with problems then how do I know the more expensive unit...

    EG4 6500 car charging problems

    I don't have Home Assistant. Also Solar Assistant has a graph for the voltage. I was needing to take a look at the output frequency. Is it available in Home Assistant?

    I wish they would put it on one of the graphs so you can see it over time.

    EG4 6500 car charging problems

    It is for a garage so the only thing I have connected is an air conditioner and a RV so I have not noticed any other problems.

    EG4 6500 car charging problems

    Both batterys and grid are hooked up to the inverters. It does not show a voltage drop in solar assistant. I wish solar assistant would show the output frequency so I could check that. The chargers are for chevy bolt and I also have a Walbox charger. I also have another Growatt system that has...

    EG4 6500 car charging problems

    The inverters do not show any alarm. I usually don't reset the inverters; I am resetting the car chargers to get them going again. I can usually see in solar assistant the spike in voltage when the solar panels come out from behind the cloud is the same time the car charger alerts me there is a...

    EG4 6500 car charging problems

    They don't tell you actual error code they just have a red light that turns on to show you that there is a problem. I have to unplug them to get them started again.

    EG4 6500 car charging problems

    I have been having a problem with 2 EG4 6500 set up in split phase. They have been working great except for 1 problem. When I am charging my car and the sun goes behind a cloud my charger will throw an error and stop charging. I have tried both 220 volt chargers and 120 volt charges and they all...

    Growatt 3000 LVM possible inverter issues

    I have had the same problem with the flickering led lights for about a year and I was out mowing my yard and I noticed the ground wire attached to the grounding rod on my utility pole where my electric meter is mounted was loose, so I tighten it up and I have been flicker free for over a month.

    Big Battery 24V inconsistencies

    I have 8 of the 24 volt hawks and I had to balance the cells and do other repairs before I could get the correct voltage from them. I still have one with what looks like to have bad cell that I am currently repairing. They refuse to send out or sell replacement parts so the only way to get them...

    Big Battery 24v 170ah hawk problems

    I just called Big Battery today about a warranty issue and guess what. The still treat there customers badly.:mad: All I need is one 170 amp cell to fix one of my battery's and they will not sell me one. They have the worst customer support I have ever seen. I am willing to pay to fix the...

    Bigbattery 24v HWK not powering on?

    >I had about 500 watts of consistent load connected to it (just a router and a small server) so definitely not pushing any limits. 500 watts per hour plus inverter usage of about 60-65 watts per hour = 565 watts So If your making it until 4:00 am your doing pretty good. Here are my inverter...

    Bigbattery 24v HWK not powering on?

    You will need to put it on a battery charger to wake it back up. If it doesn't come back on you will need to send it back in for warranty or repair it yourself. You need to fully charge it again and see what voltage it actually shuts down. If you have a bad cell or 1 that is out of balance it...

    BigBattery 12v 170AH in series balance issues.

    I have been going by the spec sheet. I set 29.2 as bulk charge. They wanted me to set float and 29.2 as well but I currently have it set at 27.2. So that would be 3.65v and 3.4v. Resting after 24 hours they seemed to be around 26.3 to 26.4 when I got them but I think they are doing better now...

    BigBattery 12v 170AH in series balance issues.

    Yes I opened them up. I had already returned several and I ran into some more problems. Most of my problems were quality control related and could have been prevented. So I decided to save shipping time and money and fix them my self. The components they use inside the battery look pretty good...

    BigBattery 12v 170AH in series balance issues.

    Hi He has 4 12v in series and I have 8 24v in parallel. Since the cells in all 8 of my battery's were out of balance he may be having the same problem and causing BMS problems.

    BigBattery 12v 170AH in series balance issues.

    I had to charge the cells individually to get them in balance. I'm still working on 2 of the battery's but the other 6 it seems to have worked out well. I also had to add some washers to 4 of the battery's where they used to small of washers. You will also need to check the torque on all of the...

    BigBattery 12v 170AH in series balance issues.

    Hi The cells may be out of balance and causing problems. I have 8 of the 24 volt hawks and every battery has had out of balance cells. I had one of the battery's that 2 of the cells were fully charged and the other 6 were around 3.29 volts.

    Big Battery 24v 170ah hawk problems

    Hi I started having problems with another one and found 1 loose nut and 2 that look like the washers were going to pull through the board. I added the correct size washers and balanced the cells out. The torque specs on the nuts were all over the place probable because they didn't use the...

    Growatt settings

    So far they have worked as advertised. When the battery's get low it will switch to grid and charge the battery's and then switch back. You will never know its happening. It's very helpful in the beginning to use the Growatt website to monitor with but you really don't need to.

    Growatt settings

    So far it is working as expected. Currently we have about 7 kw feeding 3 of the inverters. I have another 10 kw of panels setting on the ground ready to add when the weather cools down outside. I will be adding these to the remaining inverter and 2 growatt 120 amp charge controllers. I think we...

    Big Battery 24v 170ah hawk problems

    Thanks for the help everyone. I put washers on all of the studs and charged the 2 cells up to match the rest and it seems to be working ok now. I did a 90 percent discharge and the voltage on the cells were still pretty close together.

    Big Battery 24v 170ah hawk problems

    Hi Its really a bad design. You can't even tell the battery is working after you plug it in with the rest of the pack. The battery can be turned off but it will show the pack voltage and the power light will be on so you thing everything is ok. This one has probably been bad since I received...

    Big Battery 24v 170ah hawk problems

    Hi They will fix it if I ship it back. They also said I can dispute the shipping charges if it is there fault. But the only way you can prove it's their fault is to open it up to find the problem. Since they have a sticker that says it will void the warranty if you open it they can easily say...

    Big Battery 24v 170ah hawk problems

    Hi They have been having some problems but I really have been ok with them. They have been nice on the phone and good to work with. If they would just sell me some parts and help diagnose the problems instead of having to spend money on shipping I would be happy.

    Big Battery 24v 170ah hawk problems

    Hi I might not be understanding correctly. I can check the readings of the cells but the BMS does not have a software interface. Is there some other way to check what the BMS is reading?

    Big Battery 24v 170ah hawk problems

    Hi I added big washers to all the cells but I did not think to check the temp's first. That would have been a good idea to check first.
