i have 24 385 W panels. I did not have good results with input voltage over 300. If I'm under 200v with double the amp input, I produce much more power. I put up a post regarding this last year but it went nowhere.
I'm running two EG6500's with DIY 48v 280a JK bms 16s batteries. I had an over temp in a hot garage in the summer in the hottest state in the US. I leave the lower covers off in the summer and a fan pushes the exited hot air away so it doesn't make it's way into the inlet. No problems since...
Just a flicker on a few bulbs regardless of load. Washers are brutal. Not a high load but the up and down. I don't have a problem with my washer though but I make sure I keep the loads some what low, rarely above 4500w. I know they can do 6500 but nothing is happy running at max.
I'm running two 6500's. 3.5t a/c is on a soft start. Pool and Water heater both (120v) are offset timed. I just make sure the ac/ doesn't come on when the dryer is running with the pool or H2O. I get the flicker too.
I used Iron Ridge too. I found a local place that carries them and others. It was less expensive using their aluminum racking than buying steel and making my own. https://www.ironridge.com/
I can't sepak on the Sol-Ark but the EG6500's are HF too. If I went a little over max watt on an a/c start, it would shut it all down. Nothing else could be running. This cut my startup to 1/3 or less. 3.5 ton a/c starts no problem no matter what I have running...
I have this issue too with the 6500ex's. When I am not concerned with battery depletion over night, I flip the breaker off going to the inverters which forces then to consume from the batteries.
I'm running twin EG6500's. Battery type is set to "User Defined"
Float Voltage, 54.6
Bulk Voltage, 55.0, many people go higher
Equalization, disabled
Max charge current, 60a per inverter. 120a total, less than .5C to keep the batteries happy
Battery cut off voltage 47.5v
Back to grid voltage...
Temco wire. I bought on Ebay. Crimping your own ends is more than easy. You won't have to worry about buying correct lengths. MC4 connectors. I used a DC breaker instead of a fuse. https://www.ebay.com/itm/222304797420
I did paypal with Amy from Docan. There was an extra fee for something. I could have done a bank transfer but didn't want to hassle. Everything was fine.
. You are charging to 55.2v, 3.45 per cell but one cell takes a charge slower so the voltage is higher and you trip the bms. Set your bms ovp a little higher, at least 3.6v . It's a safety. It is working, you are just making it work hard. Try it then see how it goes.
Your bms is working fine, it went form charge to not charging and showed a positive amp charge to a negative back to a positive. The BMS is a safety. If you want 3.5v per cell, set your inverter to charge at 3.5x16=56v and bms over volt to 3.55 to 3.6. One cell will always be a little higher...
I know MPP has a 8048 max that is 240v too. I don't know if it is on par price wise with the Growatt. I bought from Amy through Docan, Jenny seems to get equal praise. To save a buck, you could order from them but ship from China and wait a little longer.
About budget, I was originally going...
