We purchased a new 2021 [email protected]
320 recently and I finally started trying to understand a little bit about the solar controller. As expected, the dealer put in a cheap Interstate Group 24 Marine Dual Purpose battery but did nothing to set the solar controller up for that (it was set for a default Victron AGM battery). I contacted Interstate this morning and they sent me the attached PDF to help me setup the controller. I defined a preset in the Victron app with the following: Absorption voltage: 15.9, Float: 13.15, Equalize: 16.15 and setup up automatic equalization every 30 days. I see no place to set the Bulk voltage of 14.4. I've also attached a screen shot of the settings in the app. Any opinions from the solar experts out here on my settings?
On a related note, if I sit and watch the app, I can see the solar output moving up and down on a regular basis (unrelated to cloud cover) as illustrated in the attached screen shot (VaryMPPT). Seems like odd behavior, but I'm a solar newbie! Any thoughts?
Unfortunately, I am guessing that most dealers just toss a battery in before delivery and never setup the solar controller properly. Eventually, we'll probably upgrade the battery, but no use trashing the existing battery with bad settings.
Thanks in advance for any help/comments.
