I have a three-phase ve bus system with two PV chargers.
I think I have some problems with in/out power calculation on the VRM portal.
If I take one-day data from VRM its looks like the PV to battery power more than the battery to consumption power. So how it's happening? If I take from battery-less then I use where the excess power is going?
Hi Al. How bad is it? Bad as mine?..
Flooded pb's, no BMV (so possibly a little measurement error), no dc loads. ~75% OUT vs IN.
Some loss in the Multi, bubbling off water is likely involved, the rest heat losses presumably.
Exotic batts will do better. Check for yourself, set VRM dashboard to 'last 7 days' or longer, hover mouse over the day for the daily figs.
The real world..
Hi!
I am wondering that is there something wrong in my system, because daily production is allmost double, comparising to consumption. I have 8V AGM batteries (3 x 8V@200Ah series and 2 sets paraller, 24V@400Ah)
Could this possible damage my batteries, and if so, what could cause this and what to do? I have ventilated box for batteries with thermostate and fans, and I have double checked battery specs for charging voltages etc.
Any help is appreciated
