You did great man. I really like that inverter. I built my own batteries but its been kinda a pain to do so but finally everything electric and enough capacity to do it. Good to see others on this same journey
For sure. I've been very satisfied with how everything has worked and how easy the whole thing was. I didn't even fall off the roof when I was installing the panels!
You have a great system, those sol-ark's are like the Ferrari of solar hybrid inverters. Good solid solar panel setup too (if you get the itch I'll bet you'll be thinking about adding more to improve winter solar generation next). Your battery system is also a solid win with 14.4 kWh of storage, though running independent 24V LFP battery packs in series to get 48V can cause problems (note 1 below), so keep watch on those SOKs and make sure the cells stay healthy. The sol-ark has a lot of programmability, you can completely automate the generator operation if you want to. -Matt note 1: lithium battery packs have internal BMSs that shut-off charging if cells over-volt. This can cause problems when you put them in series because if one battery shuts down charging it also stops the other one from finishing its charge. So usually one uses 48V battery packs in parallel when putting together a 48V system rather than 3 parallel sets of 2 x 24V in series. Having three sets of two in parallel does add good redundancy, but most people avoid series configurations and put 6 x 48V rack-mount packs in parallel.
Appreciate the information. I have already been looking at 48v server rack batteries and moving the sok 24v to a system in my shop where things are less critical.
Very nice system. Built great. A simple question, an off grid solar system that uses a genny to run any real appliance is no more than a system that uses generator heavy load and solar for the small appliances. Just wondering, i love s olar but price is still to high for me.. great video
Saw your comment and wanted to say yes it is expensive and I spent alot on my off grid solar but I'd say over half the money I spent was buying the wrong stuff. Once I saw what it takes to make a system large enough to run a house full time I re-bought almost everything and now it's great. It was about 30 grand in components but now... finally... two years later..... it works
No. The tigo transmitter is powered from the solark with 12v. Then the transmitter communicates wirelessly with other transmitter/receivers with each panel. Hope I answered that well enough.
@thefarmwrestler Thanks for answering, I guess my question is this, pannels are DC, you hook them into tigos, tigos output DC or AC, and what do you feed back to the Sol Ark also where(Mppt/gen input).
@leeshively669 the tigos with each panel just allow the DC current to pass through. The generator send ac. The solark just sorts everything out. It can figure out what to do with any current coming in from any source. I think the maximum input from a string of panels is 600v. I'm not an expert by any means but hopefully I answered your question
Thanks again, I have been looking at them for a min (went from 3x Eg4 6500ex to 1 SolArk 15k, have 6x stings attached, 6 min 8 max. Always feel as though I have 20-30% less power w/ 3x Mppts missing, Still do 45 to 50+KW a day. 16.5kw array all over the roof nothing facing direct South, and some shade on them at various times all day. So looking for a way to work this out, either Tigos or Victron 200/450. Glad u found you and check your videos keep.on teaching.
