    CNswipower 3200-watt 24-volt high-frequency inverter

    I just hooked up our 24V 3000W version of this unit, yesterday, the one with the LCD screen. Haven't run any loads other than a few lights so far, but looking forward to doing some real testing. The 3200 watt model looks far more beefy, seems almost double the height of the 3000w. I'm really...

    Lapping PV panels to create water shedding roof. Thoughts? Comments?

    No, I have not used these yet. I do plan to use them (or something highly similar), for a future greenhouse build, but that's a ways down the road.

    Lapping PV panels to create water shedding roof. Thoughts? Comments?

    Something like the trim used to seal between polycarbonate sheets on greenhouses may work. It looks highly similar to what you suggest: https://www.duralightplastics.com/10mm-aluminum-base-cap-anodized-finish.html

    Looking for some info on Santan Solar used panels.

    We recently ordered 10 Sharp panels from Santan. Santan told us the freight companies wouldn't come down our street, so we had to pick them up at the local freight terminal. That was fine, except they somehow routed it to a terminal two states over, who called and asked me when I was going to...

    Litime Lifepo4 Batteries - Rebranded Ampere Time Batteries?

    I was eyeing the Weize batteries myself, for the same reason as you. In the end, since I am setting up a 24V 200AH system, I came to the conclusion that it would be easier to keep two 24V batteries in parallel balanced than two (or four) 12V batteries in series or series/parallel. Weize didn't...

    Litime Lifepo4 Batteries - Rebranded Ampere Time Batteries?

    To add a couple more details, I found that I was able to download the LiTime user manual directly from their site without jumping through any hoops, which I much appreciated (and which frankly should be standard procedure). AmpereTime requires that you email their service department to request a...

    Litime Lifepo4 Batteries - Rebranded Ampere Time Batteries?

    I just ordered a couple LiTime 24V 100AH batteries on eBay, the sale ($100 off) ends today. The seller is 'amperetime_us', who also is selling Ampere Time branded batteries. I'm 99.9% sure these are the same company. However, they do have two completely separate web sites - amperetime.com and...

    Ampere Time 48V 90Ah Lithium Battery - $1200 at Amazon

    Thanks for that! I had actually not thought to look on eBay for these types of batteries, even though I buy a ton of other stuff on eBay. While browsing the LiTime, up pops an ad for the Power Queen, whose batteries (various voltage and capacities) are just slightly more. Redodo, who has been...

    First Datapoint/Review of the cheapest Amazon 100Ah 12V LiFePO4: FEENCE

    These look just like the Lisuatelli batteries, which are fairly well reviewed and $10 more. The Lisuatelli supposedly have a low-temperature charging cutoff in the BMS, but I'm not sure that's been independently verified as functional. Even the wording and poor punctuation/grammar on the labels...

    Hybrid Solar Inverter

    I have been in communication with Sungold Power for the past few weeks, discussing different inverter lines, and they have been extremely responsive, usually getting back to me same day or next at the latest. How long have you been waiting for a response? I know quite a few of their off-grid...

    Change my Mind: Why buy server rack when you get 4x Chins/redodo/amperetime 100 shipped for $500 less?

    This is apropos for me, as I've just started looking into doing this exact thing, four 12V batteries in series to make a 48V bank. Even when you factor in some extra cabling and a battery equalizer/balancer, it looks like you can still come out significantly ahead, how much depends on what sales...

    CloudEnergy 12.8v 300ah cl12-300 Battery Tear Down. Look any good?

    Thanks for the detailed write up and pictures! I have also communicated several times with Cloud Energy, who were very responsive, although not always clearly understanding of my questions (believe it was the language barrier). I was considering the 25.6V 150AH battery. Had kind of decided...

    150ah lifepo4 rack battery contender enters Amazon! $1699?

    I know this was started with the server rack battery in mind, so hope it's ok that I'm discussing the standard 25.6V 150AH Cloud Energy. I could not find out anything about this brand via the usual search methods, so I figure every little bit helps. I did receive the spec sheet for the...

    150ah lifepo4 rack battery contender enters Amazon! $1699?

    This is very timely, as I just discovered this brand myself. Currently looking at the 25.6V 150AH model, myself, which seems to have a number of features not found on the low priced (non-server rack) LiFePo4 batteries...
