Esteemed Wrenches; We recently inherited a "problem off-grid system" from another local Wrench. We didn't steal, he fled and said "have fun." It's all Xantrex, and impeccably installed, but we do not install Xantrex and are just learning the menus and such.
This system gets hit pretty hard every night, and we want to do regular battery equalizations. Though the client is pretty good on adding battery water, we really don't like automatic equalization routines.....bad timing can mess everything up. The client refuses to install a backup generator of any kind, so we need to EQ via solar on sunny days. My question.......I had thought the Xanbuss system let everything talk to each each other and get along happily. The "Equalize" button on the inverter looked like a perfect solution. But according to the previous Wrench, a sinister passage in the XW user manual and a cryptic and disjointed phone call to tech support after over an hour on hold, XanBuss can't make this system equalize via the PV controllers? They *each* have to be manually set individually to do it. This is WAY over the head of our client. It scares me. And there has been lots of sticker shock for the client on getting everything working as well as it has (blew thru an undersized set of AGM batteries in a year) I don't think I can sell a battery maintenance contract. Raised eyebrows and a "harrumph," I can just see it. So did I miss something here about a Xanbuss system being able to EQ via the dual PV controllers? Or do I really have to train this client to dig into BOTH the PV controller menus every 2-3 months and hopefully not mess anything else up? Or, should I just plan on bringing my Honda 2000i every couple months to EQ, or hope for a sunny day, and hope for tea and cookies, if not a maintenance contract? Thanks in advance. I'd be shocked if the Xanbuss system was so townie-oriented as to only easily equalize via AC mains. With an Outback Mate I can EQ from either or both. But I've been shocked before. And her tea was good, haven't tried the cookies yet.
