And then we got the new EG18kpv 12kW ...? It does have a lot of things going for it,..I gotta admit it is tempting. (Tim - were you even a little bit tempted?)
I don't really have room to put two more inverters. I'm working in a space between two windows in the garage and I've already got the transfer switch, breaker panel, and a separate breaker panel to control grid input. I could move the latter but that doesn't gain enough room. Or I could go above the first two inverters but that's not going to be fun to mount or connect or service. I'm not doing that. But I haven't pulled the trigger on anything just yet. As Tim just pointed out in another thread, the 18k is designed to be grid tied. If I really want to make sure I never export to grid I may need to look at off-grid inverters only, such as the LV6548. But I'd really like to achieve that redundancy so something that is 240v output. I'll still be very interested in how your SCC connected to the 6548 performs. The 250v PV limit is just a royal PITA. But the 6548s won't go to waste. I have ancillary solar projects on my wish list once I'm done with the house. I do have other buildings here. They all seem to cry out for solar!I'd add more LV6548's if I needed more output, cost $2099 for a pair. As for PV, one could simply add another SCC for about $400 if you need the higher voltage, however I will report what I find running a higher voltage PV input gains. It isn't that great, early results show maybe 2.4% at peak output. Paralleling strings would be more difference (that is power loss) but if you simply double the amount of panels in series it is only the 2.4% at peak output. Most of the time it is less than 2%.
$2099 to add to your existing vs $5600 x 2= $11,200
You must have an oil well in the back yard.
you heard it folks, even Tim is tempted by this new unit! LOL.Oh, I was very excited about it's announcement. (Except for the naming)WOW!
To bad they didn't design something around the old days of building a PC...WOW!
I wonder if they are working on other versions, perhaps a larger or smaller output version.
It is super interesting to see the direction the Inverter product technology is going, lots of great features, competition to the Sol-Ark at a significantly lower price point. I am encouraged that we are just seeing the beginning of a long run of improvements, features and prive for value.
As you said earlier, it seems I always buy into a product just as a better one comes out; I decided to keep with my MPP's for a few more years and just add in a third unit to bring up my capacity from 13kW to 18.5kW, although at the cost of even more idle stand-by consumption...LOL. I can see more PV added in next year.
More like a Caterpillar vs Sany; one has been around for a long time with great reliability, rarely changes models, and has part support out the wazoo. You pay for CAT; but that comes with great parts support.
You might be right, IDK. My parent's still serviceable 25 year old Trace unit reminds me of a 1970s Pioneer receiver. Replace the caps once every half a century and call it it good.
Mine are high frequency. lol
Are you running any high surge inductive loads?
A/C's, air compressors, and shop tools.
Maybe I should have gone that route. Right now I have the 6k Growatt in service with a new 12k unit still on the floor. Haven't figured out how to get it on the wall yet. I think it comes in around 165 pounds
Engine lift?
I was thinking of that. I bought a chain hoist but not sure if I'll be able to get it high enough. I'm pretty resourceful and not afraid to try something dumb but I'm 62 and my wife is 68 and we really struggled to get the 6k Growatt on the wall.
Oh…I just remembered what we used. The heavier hydraulic cart from Harbor Freight (they have two versions. 1000 lb and 500 lbs capacity I think). I use the crap out of it so it wasn’t a single use purchase.
Yep here it is pictured with my electrician. It can’t reach super high, but it helped immensely.
Lol. The dude is pretty hefty. He’s in his sixties still doing bodybuilding and lifting competitions. Former Ranger Battalion (and more importantly for me, former industrial AND residential electrician and retired power plant administrator, who also does dirt work on the side of his side hustle).
