Hello Everyone- Newb from South America.
I would appreciate if someone could help me with calculating the number of solar panels I need for my off grid system. I recently I bought a MPP Solar inverter model PIP 8048Max 48V MPPT, and I am in the process of buying the panel and batteries, I calculated my daily use of power at 20 KW. The spec for the inverter is the following:
- Rated power 8000VA/8000W
- Nominal output voltage 230VAC
- Frequency range 60Hz
- Efficiency peak 93%
- No of load power consumption <70W
Solar charger & AC Charger
- Max PV array power 8000W
- PV inputs 2
- Recommended Min. PV input 100 VDC
- Max. PV input current 18A each
- Max PV array Voc 500 VDC
- Max. solar charge current 120A
- PV array mppt voltage range 90Vdc – 450Vdc
- Start-up voltage 80V +/- 5Vdc
I am planning to buy Trina Solar panels 500W, reading the specs I got confused with the STG and NMOT data, I never done a PV system. The info I got from the data sheet for NMOT is:
- Max power – Pmax 379WP
- Max power voltage 40.4V
- Max. power current 9.37A
- Open circuit current ISC 9.89A
And the batteries, they will be 4 Pylontech US5000, 48V
- Nominal capacity 4800
- DOD 95
- Usable capacity (Wh) 4560
- Discharge voltage 44.5 – 53.5
- Charge voltage 52.5 – 53.5
I want to start with 4 batteries, and I would like to know how many panels I need. I live in a remote part of Peru, and I don´t have many options. I never done any PV system before, my house currently use a generator, but it is too noise and my wife complains about it. We use to live in Los Angeles, retired and decided to buy a piece of land here. It is beautiful, clean and quiet, but sometimes we miss the Good Old USA.
Thank you very much for reading my post, and thank you for helping those who want to learn DIY.
God bless you.
