Two weeks ago I did a large solar install for a customer in West Texas. This install used two Sol Ark 15k inverters, 72 Trina bifacial panels, configured 12 per string, 36 per 15k. We also used 20 RuiXU 48v100ah batteries set up in two 10 slot racks. Finally, a mandatory item for those that...

i literally finished a 32 panel install today at my house using the S5 rib bracket 3. Saved a few dollars over a rail based system. And saved me about 750-1000lbs of weight on my shop. It’s maybe a minor factor harder as an instead of a 40’ section of rail thats pretty similar to align, you...

I’m looking at a separate solar system for a pool heater thats electric. I need a heater that’s about 120kBTU. That’s about 35KW if I did the math right. Anyone did something like this as I’m wondering how many panels I’d need to power it 6 hours a day. I’m using a 450w bifacial panel. 80...

Thanks Zwy. I’ll go with the 6548 then. Much appreciated.

Use bifacials. The back is glass vs plastic. Which in hot climates is susceptible to expansion/shrinkage and over time is likely to have a small leak that will let moisture in and then cause issues. Even if there was no gain, IMO, use bifacials. As to the little extra weight vs a...

Yes. Support said I need a ground wire from the SOK ark bus bar to the house ? Abel ground neutral. Electrician should be here tomorrow morning. Hopefully it’s a quick 30 minute deal and I’ll be operational sometime before noon.

Today we have everything connected. Right before I flip the SOK ark 15k internal load breaker on, everything appears to be working for 1-2 min then I get an error. GFDI relay error. Anyone have an idea? As a note I have a main cut off switch, and have a manual 2 pole transfer switch...

Out of town now but yes I can do that. DM me if I forget to do it tomorrow.

I have one Sol Ark 15k inverter and have 32 Canadian Solar 450W CS3W-450-MB-AG Bifacial Solar Panels. Down the road I will add another inverter and more panels. To maximize the amount of panels per inverter, what would be the best way to set these up in parallel / series? I was thinking 7...

I’m going off of what Victron, Growatt and many others have stated ano published. Split phase is needed. But yes I need to find someone in the US.

Dan thanks for this. When your running no grid power and using battery, do you still get 6000 watts flowing across L1/l2? 3000 per side? And I want to put a generator into this so I think I need a transfer switch. Then run that into the inverter.

this Im this is the panel.

Here is the inverter.

Yes I cant run everything off the generator but that would be fine. Worst case I plan to set up a connection from. My diesel truck (2 heavy duty alternators) and can use it to charge the battery bank. Do you see a need for the 6048 vs the 6548? Appears to be the same price. Not sure (next...

Also, is there a nice screen like Victron has, the GX50, that shows all the power flows?

So 7 in series per string is what I thought as it will get below freezing in Dallas, TX area.

Initially I’ll start with 7 panels and will add a few more down the road. That will deliver 7x400 watt or so. Using the used San tan panels.

What display do you use? Will the Victron work with MPP? As to the panels, nothing is hooked up yet. I planned on using dedicated mppt controllers.

Like what? I want to use a name brand but an economical price point. MPP seems highly recommend by Will and many others. Don’t see an inverter for the wattage I need without the built in MPP.

As you pointed out I would overload the mppt inside the inverters. Using SanTan used 400 watt panels.

Ok guys much appreciate the help. This thread has me learning a lot. Will go for the 6548. Id love to do Victron, but the inverter alone is 3x more and also requires many other components that add up. If we lived full time in ours like Lt Dan Id do it, but we use ours for trips and spend...

Ok thanks. I’ve been stressing about inverters and that’s as far as I’ve gotten. Much appreciated as that will save costs.

One question, from reading above it seems the 6548 is the way to go If I only do one inverter. Down the road if i want to add another inverter for redundancy, would there be anything wrong with adding another 6548 or woudl i need to toss that and go with two new inverters (todays tech) 6548?

Engineer775 did a video about a week ago that has about 40 batteries (213kw) connected in parallel to a pair of 15ks. Treat them like one huge battery thats 48v100ah. Guy that paid him dropped a crap load on just the batteries.

The 6548 has two AC inputs? One for shore power and one for the generator?

Ok I just re-checked and didn’t see the 2nd AC input. When you say combine them, you mean take the wires from each and plug into the AC In on the inverter? That wont cause an issue from grid power flowing onto the generator out and going into the generator thru the AC out?

Dan doesnt have grid power so only generator, which I’m guessing is plugged into AC In on the inverter. Dan can you confirm?

The cost of the heater isn’t the big deal. Rather it’s the cost to run it. Propane is over $3/lb. So that’s $25/day. Electric would be similar or higher maybe.

This is for RV (camper) use. I have plenty of room and no issues with weight And have lots of EG4 batteries. Want to focus on inverters only please. RVs have a 50amp grid power plug. This is different than houses. So my question is for those that understand what split phase is. There is no...
