Thanks. I went ahead and ordered them. I will open the hood on them once they get here.

I am looking to pick up 2 of these. I couldn't find any info, anywhere on them. Manufacture claims to have a propriety BMS. 24V 200Ah LiFePO4 Battery 24V Lithium Battery, Built-in 200A BMS, Max. 5120Wh They are the fastest ship date and a fine price. I just need something to replace dead lead...

If it bothers them enough, put them in a shed. Problem solved. Best part is, we don't need a bunch of gov bloat to hold our hand and make us feel safe.

Maybe they should stop building used 18650 power walls with legos and sears soldering irons.

The title of the tread pretty much sums up the situation. Started in the 80's and now has become a cult following.

Do you have genny you could run while you hook up those panels? Been there done that. I went off grid two years ago. First summer with almost no gear was brutal. I think I spend $800 on fuel in one month. Gas was over $5 a gallon.

Well I think I pointed out some pretty good things, let me know if anything that I said is not true and I will correct it. HFs are pretty good now a days but I don't see the point personally. Still not going that route,....ever.

This is very true! The FETs on either system still have the pedal to the metal but its that sharp spike that is really hard on electronics. There is SOME extra kick with a transformer that is not there is pure direct FET switching. The transformer "lag" also prevents less shorted load through...

More then likely and "open" FET is the case. Thats just the common failure mechanism in general. I have heard rebuilders that have seen shorted but they see a much higher volume. There is more to consider then just a shorted FET. I look at the overall picture. I think a transformer outputed...

Thats amazing. I still would not buy an inverter without transformer isolation. Just can't do it. Sorry. I want a well built truck not a Ferrari.

The "flywheel" affect is just one aspect and I agree, they are making the HF inverters pretty well driven now a days. Still, I will take a pass on HF inverters. Maybe for a random use but for my home, I don't see any advantage. I want my gear robust and HF is not that type of design. Sorry to...

I believe the FETs are at around 180v DC to get your 120v wave form with over head included. They drive the wave form directly so no, there is NO isolation. Pull up a typical HF diagram and you will see with your own eyes. So, one shorted FET and you have 180v DC on your home mains. This is not...

You are really poking the hornets nest with this one......should be an interesting thread. You need to go back in time if you really want to understand the reason we have HF or what is a better term "no transformer" inverters. Think cheap gear from China back in the old days when inverters were...

If you figure out how to EASILY get the lead into a more pure state out of used batteries I would love to hear. I would make some solid plate DIY batteries

Yea, it seems to be about $500-$600 more. You would likely be fine since you have been on the 1.2k Samlex. Your system design will make it easy to add gear later and you could just add another 3k down the road.
