September 4, 20241 yr Hi, I am Aubrey Kruger, residing in Klerksdorp, North West, South Africa. I have the following questions: I have 9 x 250W - 270W solar panels. They are coupled 3 x 3 in series and 3 strings in parallelle. I was told that with the SNA5000 I should have all 9 in series and one sting [4 gauge] to connect to the SNA5000 Inverter. Is it true? What size Fuse must I install? What is the best circuit breaker to install between panels and SNA5000? I have 4 Pylon Li-Ion Batteries. 2 x 2000B 2.4kWH. 1 x 2000C 2.4kWH and 1 x 3000C 3.5kWH. The comms is coupled from 3000C to the Inverter. Will this work with the SNA5000?

Will this work with the SNA5000? 3 panels in series has too low voltage(3 sets in parallel does not help) . 4 might be marginal and work but only later in the day. Rather use all 9 in series on 1 MPPT. Batteries I cannot help.

Just check protocol and cable pinout. luxpower-compatible-list（LXP-3-6KSNA-ACS3600）230826.pdf (luxpowertek.com)
