Outback Radian 8kW or MPP Solar pair for 13kW?

[Lstyles]

I had the same question as the OP about two mpp solar lvx6048wp vs Outback 8k. I know the outback’s are great units but I like redundancy of the two lvx (and I can afford to buy an “extra” one for back up and still pay less than the Outback). I know it’s an experiment but I saw Will P use the Mpp solar units and he doesn’t usually mess around and use poor quality items. Lastly my use is for a vacation home and so if all hell breaks loose I can just go home or to a hotel!

I'm partial to Prosolar racking with your whatever needed type roof mounts. Dollar for dollar you can't really even DIY Rails for the price of a Prosolar rail. Unistrut is another cheap option but its only slightly less than Prosolar and u can run into the issue of what to use for end caps.

S5 makes a great line of roof mounts. I've used the versabracket 47

Signature Solar makes a budget friendly mini rail but honestly I look at it and think, how exactly do I do zip tie cable management with these?

These small clips for securing PV cables to panels from Signature Solar are better than tie wraps! Easy to use and install and durable to withstand nature!

Update: I ended up going with a Growatt 12kw. It's a transformer based low freq inverter. Heavy as hell, but it can take a big surge. Probably overkill. Priced well, but to do again, not sure if I'd go Growatt. I tried to register the unit,and ran into so much trouble just doing that; so not sure how support will be. Still, a lot of people have them, and have them running. It's a 250vdc max on each of the two pv inputs. I hear newer units go up to 450vdc (which would be nice), but I think those are high freq inverters. Would have gone Sol-Ark, but this is not a "live there the rest of my life" install, so I couldn't justify the cost.

Nice. I'm just finishing up my install off the growatt 12kw in a cargo trailer for our off grid farm

Growatt SPF 12000T 12kw Inverter Cargo Trailer Install.

Installing The Big 12 kw Growatt into a Cargo Trailer for a 12k watt mobile power generator. All the panels will be installed on a pole/post barn and I will connect the Inverter's Solar Charge Controller MPPT to the panels via 8 awg SOOW cable and Anderson Connectors. First phase of the 11.8kw...
