new camp setup

run all my dc loads(radio,water pump,ect) shud blow long before the internal 40a controller does.
ct) from the 40a load connection.have it fused with a 20a inline.works awsome.
the 20 a shiu blow long before the inetrnal 40a the controller has.

finally got everything installed.
in batttery bank pic i added mrbf fuses,at the time of the pic i didnt have them all.
so far i'm totally impresssed.
was at camp 5 week and used maybe 1 gallon gas runninng gen now and then to fill water tanks.
my original plan was to mount the panels on the outside wall but i didnt like the way the mouints held the weight of the big panels.
its 7/16 obs and u used leg bolts but soon as i let the mounts take the weight i could see them pull.
so went with option b which was to mount them on the patio railing.
this actually worked out better as the 2 big panels are bifacial(all i could get at the time) and start charging early in the morning from the rising sun hitting the backside.
its not ideal for winter as the will get buried in the snow but i dont goto the camp anymore during winter(i aint young aymore).lol
in nov when i winterize camp will shut the system down,gel's have a low discharge rate and will be fine until apr/may.

going by the controller kwh output the 2 big panels(545w) put out double the power as the 2 smaller panels(410w).
bere i left i checked it and it showed about 19 kwh for the 2x410w and 37kwh for the 2x545w panels.
 
only regret was not getting a little bigger inverter.
my old one was a 20 yrs old modified sinewave 1250w which could run the microwave(1200w)
new one is a pure sinwave 1100w which cant run it.
seems a 1500w inverter doesnt exist anymore,next bigger to the one i got is 2500w which i would be under cabled for.
plus its 300 plus dollars(canadian).
i like it as it has a wireless remote control.
think i'l just buy a smalller microwave(700-800w) range for a hundred dollar range.
 
most morning bats are at about 12.4-12.5v by 10-11am they are back to full charge before i even get any direct good sun.
all day long they stay at float(13.6) after 3 hrs at 14.2 bulk.
i dont like the renology shunt much,i may buy a victron when i see them on sale on amazon.
 
i would like a opinion on this though..
i grouped batteries in 2(parallel)
then from each group to buss bar.
so 8 bats,4 groups.
when i added the mrbf fuses i thought why fuse each battery(i bought 8).
i ended up with using only 4(one for each battery group)
fusing each battery didnt make sense to me.
if one battery fails i'de sooner loose the group rather than a single battery.
to me(my thinking) a single battery will hit 100% soc first and goto float and the other group batteries might not be there yet.
?

Using a fuse for each battery string is correct. When 2 batteries are in series, its basically 1 battery, if the fuse opens the circuit is open all is safe.

You can add another inverter to the same system. I see it often for large/small loads so they can turn off the high consumption inverter when not in use.
 
they r parallel not series
and thank you re inverter.
1100w runs my daily needs
so to be clear it works.
at camp 3 mths
didnt use 1 gallon gas.run it ofr 10-15 min ti fill water tanks
if it wasnt through well case(i have dig up)
i go with a newer soft start.

back in 2000 is when i did this nothing existed.
 
well for as little as i need run gen.think i stay with it for water
dont even remember last time i changed its oil.
crap champion 4500,a briggs and stratton walk over this.
but was cheap on sale.
sure well overdue

When generator dies, I wouldn't hesitate to get a LF inverter for the well pump. The load is momentary, and you will recover batteries in short time.
 
you sir are a god.
i had no idea about low frequency inverters
Be careful what you get. Going too big will have high idle consumption.
I just installed a 12v/2000w Aims LF and measured idle was 26w. Considering it can surge to 6000w for 20 seconds, thats not bad. But say a 6000w unit that can surge to 18000, idle is over 100w. That adds up quickly.
 
thank you.
i was actually looking at a aims on amazon.ca
it looks same as the sungold?
i think same manufacturer relabeled?
i was looking at the 12v/3000w.
They are all rebranded Sigineer. Right now the best deal is direct from Sigineer, free shipping and the remote display is included as well.

Im an Aims dealer but with free shipping, its cheaper from Sigineer than my dealer cost. My order from Sigineer last week arrived in 4 days. Sorry Aims 🤷‍♂️

I like their inverters, mine has been at camp for 7 years now, no issues.
 
u got me so close to buying one of these.
12v/3000w i think shud do it.
gen that runs pump is a 3450/4550 surge.
i had a older generator that ran pump also fine(was a 2800)
so i think 3000w with its big surge ability shud do it.
only thing stopping me is i only at camp till end of the month.i winterize and close it up till spring.
i will definitely be getting one over the winter for next year(keep eye on price and maybe get a deal).
built in transfer switch and charger is a bonus.
should be no need to lug gas anymore.i do always have 5-10 gallons on hand for lawn mower and if gen needed.

again thank you.
i have had solar here for 20 yrs and never realized about a low frequency inverter.
they are awsome and what i need from reading about them.

Yeah, I use a 24V/4000W Aims LF. My well is 50ft submersible 1/2hp / 120V set at 50psi. The lights in the cabin flicker when it starts but no real issues. The TV doesn't skip a beat.

What kind of well pump do you have?
 
its a craftmans(sears) from like 2000.
i have the manual but i says anywhere from 1/3 hp to 3/4 hp(different models)
i honestly dont know what mine is.its been down 275 ft since 2000 ish.
guy who drilled well has little water at 60ft.said flow wasnt enough.
so i said ur here keep goin.
he only had 300 ft rod.
i set mine at 70 psi
i have 100 gal storage
only need pump water once every week or 2.
10-15 min fills tanks

240v i assume?
 
i bit the bullet and ordered a aims 2500w/7500w surge today.
was reasinoable i think.
1100 and change cdn shipped from amazon.

Things must be much higher in Canada! $654 here in the US.
Anyways, it should be a good inverter for you. Use your generator for AC input in case you need to charge batteries in the winter/cloudy/rain season. Dip switch needs to be set to AC priority, see manual.
Report back on how it handles the well pump.
