That Nasally Guy
New Member
I have an EG4 3000w 48v 3n1 inverter/charger and two 5kw Rubix 5kw batteries. When I first wired the system up to my bus I was charging the batteries with a small Pedator inverter generator. The batteries would charge up to about 92% (with about 5-6 amps coming in from the generator) before the amps in would be cut to zero by the EG4. I changed a setting in the EG4 so that it would send 9-11 amps from the generator. The batteries would charge faster but then the EG4 would quit sending current to the batteries at about 82% capacity. Then I got my panels set up (eight 380W in series) and they're making good power - I've seen up to 25A going into the batteries but now the EG4 cuts current in at 70%. Why is this? I talked to the Amish guy I bought the system from and he kind of explained it but I'm skeptical. Also, I have a friend with an EG4 controller/inverter with EG4 batteries and he said when he connected the comm cables from the batterites to the charger/inverter it automatically changed a buch of settings and he sees 99-100% capacity all the time. I currently don't have any comm cables between my charger and batteries because the Amish guy said I didn't need them and the cables that came with the system don't have the proper jacks (I think) to go between the two.
Should I set the original setting back down (slower charging but higher capacity)?
Should I get the correct cables and let the charger and batteries talk to each other?
My batteries have RS485/CAN, RS232, and RS485/RS485 jacks that look like CAT5 phone/computer jacks. The EG4 has an RS485 that looks like printer USB cable jack and an RS232 that looks like a CAT5.
Maybe one of the short gray cables on the right f(see attached image) from battery to battery and the gray cable w/yellow jacks on the ottom left from EG$4to batteries?
Any thoughts/help?
