thanks for the correction. i did figure the charger for 10 amps because i don't yet know what the charger puts out yet. just got it yesterday in the mail. will hook it up today for a test. the specs. say 10 to 15 amps. i haven't checked the actual battery capacity either. 10 amps would be...

look at this pdf at the end of page 3, start of 4. with this module all the cells are wired in series and the best system use is for 500 volts out.
look at how easy it would be to re-wire the ten cells in parallel for...
my math correct? you pull in 2260w x 5?hours = 11300wh during the day. how many watts does it take to run the minisplit? multiply that
times 24 hours. if the mini takes more than you produce; then you need more solar panels, put a timer on your mini, or have your neighbor turn on the mini...

i am not trying to advertise or represent...just letting everyone know there is another alternative. is that all right?
i just got it in an email.
the victron quattro is almost twice the cost, but i really like it because it will charge my batteries when on the grid, two grid inputs of 100a each,
and at the same time it would run my kitchen power lines. i will check out cerbo, but i think multiplus is out of the question because most of...
i bought one to test it out, but couldn't get any info. on adjusting it. 0 to 331vdc output with 220vac input. 10 to 15 amps.
really cheap and i figure it's useless, but will make a good experiment.
finding a 48v battery charger to put out 30 amps is really difficult or extremely expensive...
it might be interesting to graph the inrush current, figure the watt hours during inrush, measure the cycle time/on/off when the freezer is full,
and then compare inrush watt hours to operating watt hours.
how about plugging in a space heater to your inverter? i bought a couple of 350w space heaters with fans and i can use them to keep from turning on my base board heater...thus saving the power that the b.b. heater uses. most space heaters are 1500w. you could pick which heaters your system...
