I’ve currently implemented a battery backup system using 2 X 6000XP’s and 4 X Ruixu Batteries. See this thread if you’re interested in what I did.

Now it’s time to add my panels. The 6000XP’s have the following specs/limits that I am using in my planning:

I’ve been looking at using the attached BlueSun panels in 2 strings of 8s (one per inverter) or 3 strings of 8s.

Specs for these panels are:

If my calculations are correct. That should give me per string:

If I do 24 panels I was going to just add one more string to one of the 6000XP’s which will give me 12kW.

Does this make sense? Am I missing anything?

Thanx!!!

Now it’s time to add my panels. The 6000XP’s have the following specs/limits that I am using in my planning:

- Max temperature adjusted VoC of 480 Volts
- Optimal operating voltage of 320 Volts
- Optimal current of 17A with a max of 25A
- Max wattage per MPPT is 4,000 watts

I’ve been looking at using the attached BlueSun panels in 2 strings of 8s (one per inverter) or 3 strings of 8s.

Specs for these panels are:

Wattage - 460watts |

VOC - 50.8 volts |

ISC - 11.5 amps |

low temp coefficient -0.26% |

Impp -10.86 amps |

Vmpp - 42.4 volts |

If my calculations are correct. That should give me per string:

- Temperature adjusted max VoC of ~450V
- Operating voltage of ~340V
- Assuming a nominal bifacial gain of 10% the operating current should be ~12amps
- Optimal wattage of ~ 4080 watts

If I do 24 panels I was going to just add one more string to one of the 6000XP’s which will give me 12kW.

Does this make sense? Am I missing anything?
