SunGold Power 5,000W 48V Solar Charger Inverter | SPH5048P

So I have bought this unit for my neighbor... I started looking thru the manual, and I have a few questions:

1) Where does earth ground go? I don't have the unit, but looking thru the manual I don't see a place it attaches?

2) Where this system is installed I have at present 8 Renogy 100 watt panels, Now wired in two sets of 4 series, then the two sets in parallel.....

So 4* 24V = 96 V of a series set at 5.21 Amp..

Then when I hook the two sets in parallel I should be setting at about 11 amps... at 96V...

I am not sure if I should just leave it as is, or if I should put them all in 1 set of 8 * 24V = 192v at 5.21 amp.....

3) They have a Renogy 48v 50 amp hour battery..... I probably will move the max amp of grid charging down because they only have this one battery to about 25 amp for slow charging.... But I was not sure if the charge controller would plug into the data port of the Renogy? I am not used to having batteries with data lines ;-)


Thanks for your input.

There's a grounding spot on the case that's tied to the ground terminal on the AC input.

8s. 4s won't be high enough VOC for the minimum.

I'd go lower than 25A, that would be 0.5C rate; I'd stay around .25C if possible.
No need for the data run. Set the battery to user and program your voltages.
Note a single 50Ah battery is way undersized for that inverter.
Thanks for your input.
You're welcome.

Thanks..

All of what you stated makes sense...

They requested info about more battery, but my concern would be pairing up a 100 amp hour battery with a 50 amp hour battery that there would be a miss match of resistance in the batteries...... They don't make the 50 amp hour Renogy battery they purchased anymore... Considred having them get rid of the 50 amp hour battery and just goto a 100 amp hour battery, but they are too emotionally attached to the amount of $ they paid for this Renogy batterry..... Considered adding another 50 amp hour battery or two but I don't like mix and matching batteries.
 
I wouldn't hesitate to parallel different capacity's as long as they are the same chemistry and cell count.
I've had two 230Ah packs, a 280Ah pack, and a 305Ah pack all running in parallel with no issues.

Yeah, but the gap is wider from 50 ah to 100.. ah.

What is the minimum VOC for this unit?
