  1. Hi Rob,To your concerns, the recommended cycle of LiFePO4 battery is 10 to 90 SOC.5 to 95 will also be fine.For storage, yes, it is recomended to keep at 50 SOC.Some of the battery meter is voltage meter, which is based on the battery voltage, not accurate.Columb meter which is based on the current and calculation by time & current, is more accurate.Andy

  2. Year round isn’t a problem @Dude, we have a really modest setup here, as the roofline can’t be altered (at least when it needed replacement the planners wouldn’t let us) and its a small house and we still get enough in the middle winter days to run the house, probably enough excess to still run it overnight with a little load management. It would be trivial if we could gable end the roof as that would probably add 2 maybe 3 times the total panels that can be fitted, and panels are so stupidly cheap really… (We don’t actually have near enough battery to do so, as the grid here is good, so going off grid was never a priority, the energy company we were with actually subsidised the battery so they can do some load balancing and energy trading type stuff, get paid quite a bit every month from the battery really).

    Possibly, but if it is only used for an hour or two mow, and only half drained, that leaves 80 hours of charge required, which could be possible in a week in some climates. I wouldn’t expect the solar panel to be the sole power source, perhaps just left to trickle charge the batteries and then gets plugged in the day before it is required to top it off.Probably will get frequently filthy though…
