Friends:
I am reworking an installation with 3 Sunny Island inverters. The battery leads have no disconnecting means or OCP. I have been looking for sensible hardware to provide this and I have found some options. I am interested in any input on these or ideas I have not discovered. 1. SMA BATFUSE. I am having trouble deciding which one is right for a 3 SI install. a. The B.003 appears to have fuse positions for the positive and the negative leads. I am fairly darn certain I don't want fuses in the negative leads of a negative bonded system, and although this is my first SI install, I am pretty sure this is negative bonded. Am I missing something here? b. The B.001 has only positions for two fuses as far as I can see from the manual. c. So it looks like neither will work for me. Does anyone have any experience and/or wisdom here? 2. Midnite Solar E-panels: a. The regular panel has DC and AC components. I want to control the AC elsewhere so I could order three slave units. The Midnite unit mounts right under the inverter but I would prefer to have the OCP closer to the batteries. 3. Outback: a. We could purchase an Outback FX1000 and install three breakers in it. 4. Breaker Size: a. I have started to read the manual but I have yet to find out what size breaker fuse is recommended. Have I just not found it yet? b. Also, I have not found a specification for battery cable size. Am I blind? Thanks in advance. I really appreciate the help I receive here. I try to give as well as receive. William
