“For the sake of discussion, I will say this: *IF* this $300 (US) 2000 watt Renogy RNG-INVT-2000-12V-P2-US inverter is capable of 4000w for 5 sec, it would make it one of the best performing high-frequency 2000w inverters on the market, regardless of price.

Unfortunately, this is a huge if. As they say, if it sounds too good to be true, it probably is.”

X2 - Maybe it means 5 seconds before the blue smoke appears??

Could be, but I hope not--lol! From a bang-for-a-buck, consumer point-of-view, it would be awesome if the Renogy could produce 4000w for 5 sec. Who wouldn't want that kind of performance for $300?! Once/if word got out, it would be a hands-down best seller. Unfortunately, until proven otherwise, I'm just going to believe Renogy's official literature which says it produces 4000w of peak power. A spec that's on par with the vast majority of budget, 2000w high-frequency inverters.

OP here. Thanks for all your help. Here is where I am at with this, and I'd appreciate your thoughts:

Plan is to install 2, 100 ah lithium batteries, a 2000w inverter and a DC-DC charger. (again, just trying to power 1350w microwave as my largest load.

I'm looking at 2 possible approaches.

1.I simply buy batteries, inverter, dc-dc from Renogy so everything is the same manufacturer. Avoid any interconnection, compatibility issues.

2. I prefer some specific components, so the other option is: Buy 2, 100 ah SOK batteries. A Victron Orion 30 a DC-DC charger (Im told they are superior). Then the Renogy 2000w inverter that you guys have been talking about and recommending here.

I am not looking for the cheapest, I am looking for the safest, most reliable approach. What say you? Option 1 or 2, or a different one?
Thank you!

My approach is to buy good stuff from the start because there’s not much economy in having to do a repurchase…

Is there some reason you chose the SOK rather than say, Battleborn?

2oldman,

Price would be much cheaper for SOK

Yes, which is why I quoted what he said about cheap.

I always buy the best I can afford, and if you plan on RVing for many more years, I would buy the BBs.

It's not that cheaper products won't work, it's for how *long* they will work. My life experience is 'you get what you pay for.'.. every time.

battleborn is way over priced for what it is. the componants are being used by other as 1/2 the price and with a different formfactor (ie prismatic instead of round battery cells, even less while the technology and quality remains the same. I would argue there is more potential for something to go wring in a battle born with over 100 cells soldered in as aposed to a prismatic type with only 8 battery conections, but it will be easier to detect on the prismatic. when battle born came out they were almost the only player so they could set there pricing where they wanted.. now they have failed to drop there pricing to reflect current componant pricing so other have filled that space with quality products. what did battle born do, they launched dragonfly there OEM division for rv shops and such so they can charge 3800 cdn plus taxes for a 270AH battery. no thanks concidering I built my first 280AH battery for under 700 bucks. saving 3000 is worth learning how to do it to me haha

here is a good video from will about the 3 cheepest good quality batteries and he even mentions ones not to buy.
