It seems the reason we do not have hot water from the Blue Sky Energy inc Solar Boost 3024iL DUO solar controller, Blue Sky said the batteries are being used more. That's to say when we had our wet cells we were mostly at the marina in the States. Our refer ran off shore power and does whenever we connect to shore power.
Of course we do not connect to shore power often now so the refer runs off the new MASTERVOLT house batteries AGM batteries. So does everything else. Like our ICOM 802 SSB radio, VHF and our water maker. My breathing machine runs off the batteries all night long. Our batteries stay above 70% or really 80% most of the time with the 485 watts of solar panels and the boost the controller gives to those amps but still the batteries do not get to float state as soon and as often. That means the extra amps do not get dumped into the water heater as much or often.
Last night there was warm water. Our batteries were reading 14.35 volts on the Link 2000 .
So it is now the question of when we get the dump load from the controller. At what volt reading can we expect to get the water to heat?
Our next email to Blue Sky will be just that and then we can manage the water heater better. It is nice to have hot water for dishes like after making popcorn and the melted butter. It cleans up a lot nicer with hot water.
