People do pay extra for the 18K grid interactive features, but it works great as an off-grid inverter. Low idle consumption. Incredible surge capacity for a high frequency inverter. And the remote monitoring is awesome. After you have an 18K for a few months and you try to go back to 6500EX, there is no comparison. I would absolutely spend the extra money to get the 18K now that I've used all of them. And I have 6X lv6548's.
What was in place for all the Growatt buyers? I just watched a video from Watts247 telling me my "low frequency" Growatt 12kw (purchased from SS after watching your video singing its praises) is really a high-frequency inverter... All those Growatts were sold with major issues. Did they offer a return to buy something different to get them off the market? If they did, I never heard about it. They sold all their stock and are dropping them... I am supposed to call China? I have not installed it because I am a very green newbie and I was waiting on a video that promised to show it wired up and then the controversy of N G came along and bam- nothing. My fault for being "influenced" and not researching or waiting to see what problems come up.
I can't stand growatts. For some reason everyone thinks that I reviewed the 240 volt models. I never had them on my channel. The only model I had was that small 3000 watt unit. It worked fine but I never gave it a recommendation or put it on my website.
This topic should probably have its own thread though.
I have the pair of LV6548's installed replacing the 6500EX's and they work flawlessly. I did add a pair of EG4 MPPT100-48 charge controllers as my string voltage is over 250V. The LV6548's work flawlessly.
Still waiting on my response from July 24th to SS...
Well that's what has me VERY concerned. I DO NOT want back feed EVER. I was under the impression by setting my tp6048 to not back feed I was 100% SAFE. After all of this crap luxpower or whoever is now telling us that EVERY hybrid inverter can back feed I'm VERY concerned so this thread going on in hopes of me understand if this can happen with my unit or not is the most important piece of info I hope at this time to get out of this forum !
Yes, did test this and still need to make that video. I loaded the inverter with 12,000 Watts, and then ran my car lift that goes up to 100 amps to 120 volts. It trips All of my inverters except for the 6500. You can also start a 5-ton AC without the grid connected. I really need to talk about this more and show it
SignatureSolar might have a "refurb" / "open box" 18kwpv available shortly that you could get from them.. ?
I hope I can buy it off them haha I'll take the risk
Shoulda just had it routed down to you, would have been a lot cheaper to move it 400 miles than to Texas and back!
If there’s a grid connection thru the inverter to the inverters loads output then when the inverter stops producing power for the loads it can backfeed for a short duration thru the inverter and to the grid. I’d say if anyone absolutely cannot backfeed they need to be 100% offgrid. Shame but electric companies want anything paralleled with the grid to be up to some crazy standards in some areas. Anti islanding and a simple shutoff outside is all that should be required. My inspector and electric company might have taken it easy on me due to being an electrician who has had the inspector inspect many of my jobs.. all I needed was inspection anti islanding and outdoor disconnect. But I think the real reason I got off easy was that they thought they were going to get all my excess solar for free because they don’t give credit for backfeed in my area.. I installed a regular grid tie inverter that wasn’t zero export fir inspection and then later removed it and installed a zero export inverter. I now have permission to backfeed even though I will not be giving them my excess power. Only thing they will get is spurious backfeed
