Learned a lot about my inverter/charger from this Victron blog post. I think this is a great read for anyone who has a multi plus. But still valuable for any inverter owner.
I didn’t realize how much battery was drained by having an inverter just turned on. Every morning my battery was at about 75-80% The only thing that was on was my dc refrigerator and on ac a couple battery chargers and my microwaves clock. None of the ac devices were necessary. The blog article suggested that if I have no required AC draw overnight just turn the inverter off and just charge my battery. Now in the morning my battery is at 95% with just the DC refrigerator draw When I get started in the morning my very noisy Sterling B2B charger is on for 10-15 minutes rather than 45. Hope this helps someone preserve battery and better understand their electrical system
