Hi again,
I hope everyone had a great Labor Day weekend! I had some free time and read back through my thread and would like to ask a few more questions so that I have all ready to go when I return home in early October.
To refresh everyone's memory, I am assembling a DIY 24volt solar system. I have 8 of the Xuba 280ah cells and will connect them to a MPP Hybrid Inverter, monitoring the battery with the Overkill BMS. (Further specifics are listed earlier in the thread)
lmwilco1 was gracious enough to give me a recommended guideline but after reading back through it I would like to do the simpler version that he indicated. In this case, I will connect the main positive from my battery bank to my Tocas 120 Amp Circuit Breaker and tehn on directly into the MPP Hybrid Inverter.
I have this shunt but I do not think I need it? NOYITO 300A 75mV Metal Shunt Resistor External Shunt for Current Ammeter Analog Panel Meter as I thought shunts were mainly used to measure but does my BMS/MPP Hybrid Inverter do that already? (Sorry if I am misunderstanding)
I will attach the Overkill C- terminal (i.e., main negative) directly to my MPP Hybrid Inverter.
Finally, a question on the pre-charge resistor. Can someone give me a link to a decent one I can purchase for my 24 volt system? When I googled I mainly found 36v/48v - does it matter if I use those? My understanding is that I will just attach it to both connections on my circuit breaker for about 30 mins before I switch on my MPP Hybrid Inverter, take it off, then turn on the system.
Any downsides to doing the above? My understanding is that all should work safely and effectively by doing it this way?
Thanks again.
