Some questions about MPP SOLAR PIP-5048MGX

[TheSmartGerman]

Hello,
I'm quite new to the Solar Systems. And now I have some questions, you hopefully can answer quickly. Or can provide some references.
I did some research but, still there are still questions...

A friend of mine and I'd like to build a Off-Grid System starting with this configuration:

	friend	myself
Peak PV	9kWp (20x 450Wp cells)	4,5kWp (10x 450Wp cells)
Battery	16S1P 280AH LiFePo4	16S1P 280AH LiFePo4
Inverter	2x MPP SOLAR PIP-5048MGX	1x MPP SOLAR PIP-5048MGX
BMS	?	Chagery / Daly ?

We chosse the MPP SOLAR PIP-5048MGX Inverter for the system. But we like to extend the system step by step.

He has the need to charge his EV. I just like to go off grid step by step.

Now there are some questions:

• Will it be possible to add inverters and go from Single Phase to 3-Phase
• According to the drawings, it's possible to conecct only to one battery.
  • How do paralles charging is handled (one 80A / two 160A ? )
  • Discharging will be now problem? At maximum very Inverter will draw ~100A.
• Can I build a 3-Phase system only using 1 or 2 PV-Arrays and use two or one inverter without PV. I guess this is UPS mode?

Would be great to hear your oppions.

I know I can split the systems (MPPT Tracker, Chager, Inverter). But what I found so fare was more expensive then buying the MPP Solar Inverters.

If you have better technical solutions, just tell me.

THX

Yes

• According to the drawings, it's possible to conecct only to one battery.
  • How do paralles charging is handled (one 80A / two 160A ? )
  • Discharging will be now problem? At maximum very Inverter will draw ~100A.

Correct. With two inverters you can charge 80A x 2 =160A

With a battery of 280Ah discharging with 200A won't be a problem but I keep as a rule of thumb .5C as the max when I build a system.

• Can I build a 3-Phase system only using 1 or 2 PV-Arrays and use two or one inverter without PV. I guess this is UPS mode?

Yes you can.

Thx for your replay. Inverter was deliverded yesterday
