Its looking like we are likey going to do just this. 2 ~500w panels at ~38Voc.
Also want to thank you for noting the battery price. Ended up canceling the Kedron order and ordering 2 200ah 24v Redodo batteries, already have them at home. Saved us $700 and got us an extra 100ah.
Hi all,
We are working on setting up a 24v solar system at our off grid cabin this spring. We are typically there on long weekends for 3-4 nights.
So the batteries will be stored in 2 different ways. Off an on for 1-2 months during may-October, then be brought home for the winter and stored...
My question is more for storage at home when they are not at the cabin. We have the batteries now, and Redodo says that they ship at 30-50% SOC and we wont be installing them until the endo of may, so they may need a top up before then. At home in the basement, we will have an AC power source...
Hi there,
We are in the midst of planning our DIY solar build at our northern ontario camp this summer. We have already purchased a battery (Kedron 24v 300a) and inverter (SRNE 24v All-in One). We are now looking at panels, mounting options, and wiring and have some questions.
System size is...
They have yet to ship the battery so I may have some discourse still. When we planned this back in october, Kedron seemed like the best deal at 24v. We had planned to do 24v batteries for expandability if we wanted, as for as I understand, I would be capped at 2 12v batteries as you can't run...
This is just our hunt camp. Longest we stay up there is a week at a time max, and like I said there really isnt much draw on the power side. Mostly we are just up there thursday to tuesday over the long weekends from spring to fall. If we go up in the winter it is just a short weekend and we...
Would you worry about a higher SOC than 50% for 1-2 months? We have 400ah to run a small camp, so we dont need it full, but a cloudy weekend may pose an issue
Our Inverter/charger combo does provide some degree of battery levels with a 4 bar system. A shunt may be nice, renology seems to have a cheaper one that doesn't require an app, which may be a benefit for my parents. Guess I could get one and bring it home with the batteries in the winter.
My next question would be regarding wiring them to the panel. As I understand, 10g panel wire is good for 30 amps. the open current of the Q Cell panel is 11.26, meaning I could only have 2 per strand. I imagine this would stop me from using 2-1 or 3-1 connectors and force me to use a combiner...
The Inverter/charger will be up at the cabin during the offseason, not going to bring the whole system home during the winter.
But, point taken on the cheap charger. Thanks
Can you expand on that? Redodo sells a charger, seems kinda pricey. It is a 20amp charger and has a dead battery charging mode to wake the BMS of a dead battery apparently. Is this something you mean?

This is what I got back from Redodo.
"For longer storage of the batteries, it is recommended to charge/diacharge them to 50% level and every 3 months to charge once to 50% level.
The storage temperature for 24V200Ah battery is -10℃ to 50℃ / 14℉ to 122 ℉"
So it looks like if I am to play it...
We are talking Canadian monopoly money. Even if they shipped to canada the EG4 batteries would cost $3490 before customs and shipping. Thanks for the input though
