    So we just spent a couple nights on an island close to home and using only one fridge and intermittent lights and chargers. It's been back on shore power since 11am (it's 7pm presently) and when I pull the info up on the shunt this is what it reads. Am I missing something??After being on AC power all day shouldn't that number read 100%? I'd ask the company (actually the "guy") that sold it to me for advice but I already know it's a bust unless there is a dollar sign in his favor for a response. Brutal customer service

    Do you have to tell the shunt the size of the battery.

    After doing a little research a video online states that everything must be secured on the system side of the shunt and the battery minus of the shunt to the negative side of the battery. Does this include the charge controller on the system side as well? The controller is presently on the negative battery and not the shunt. Could this be the reason the readings are a bit off? Also should the onboard charger be on the system side of the shunt as well?

    Mine are 103 AH @ 20 hours. 

    Did you synchronize?

    Yep, synchronized them. Mine were 105 so I input the 210. We were on an island for a couple days with both fridges running, lights off and on as well as using the electric toilet, water pumps, phone and computer charging etc and everything held up great. So glad I decided to go with the panels. Just some peace of mind. I see you have your charge voltage at 13.6 and discharge floor at zero? Maybe I should change mine? My discharge floor is 50% and charge voltage is 14.6?

    I just left those settings as default. I don’t pay attention to the energy monitor/state of charge. I do enjoy watching the solar panel output though!

    I'm super happy now that I don't have to get up in the middle of the night because my wife used up all the battery power and the toilet won't flush. Not having to dress and walk her to the island toilets at 2am made this purchase totally worth it

    Me either at this point. You can buy a crap-ton of others for the price of a single Lithium.
