    *New* Inergy "Flex" Solar Generator

    I actually went ahead and canceled my Flex pre-orders (2x full units + an extra battery) - the continual delays and excuses were just too much, and I lost confidence that the company can stand behind the product. And, now EcoFlow, Bluetti and others are out with modular systems and features...

    AC200 Max & B230 Expansion Battery

    I'm heavily debating the AC200 Max and the Eco Flow Delta Max. Anyone have opinions between them? Specs are relatively similar, price-per-watt is about the same, though the EcoFlow is considerably lighter (NMC vs LiFeP04 - but 800 cycles on NMC at my expected usage is still many, many years) I...

    New portable/modular systems - Inergy Flex, Bluetti, EcoFlow , Titan - what to choose?

    Well, I decided to cancel my Inergy Flex pre-orders. I had two full Flex/battery combo's and a spare battery on order - it's been a year of excuses and delays, and I think there are now better products en route. They didn't even blink when I called to cancel - I'm guessing a lot of folks are...

    New portable/modular systems - Inergy Flex, Bluetti, EcoFlow , Titan - what to choose?

    Seems like there's a slew of portable/modular units about to come out (Inergy Flex, Ecoflow DeltaPro & Max, Bluetti AC300/200 pro, Titan 2.0 etc)- with expandable batteries becoming the norm. I'm curious people's opinions on the latest beyond the obvious stated specs - but practical usage, build...

    *New* Inergy "Flex" Solar Generator

    Just called them again - after previously being told in May that I could expect my first order to ship in June. Now... they say I might hope for July. While they extended their warranty as an "apology" for all these delays - it's hard to believe they will honor the warranty (or even still be a...

    *New* Inergy "Flex" Solar Generator

    Inergy's last public communication was that the Flex would be shipping in May (2021). I just spoke with customer service to see the status of my orders (I have multiple units I've been waiting over a year on). Sounds like they have just started shipping about 100/day right now - and based on...

    Would you buy an "open box" Kodiak?

    The short-answer I've been told (and I think this is what Inergy says) is that the Kodiak's battery is Lithium NMC - and I guess the BMS/charge profile would have balancing issues with a battery of another chemistry/capacity. Though not sure why lead-acid isn't an issue, but say, a Lifep04 is...

    Portable Mounting options

    For smaller portability - I have (2) 100w panels built into a suitcase-style with hinges. I found a tilting satellite dish pole mount (found on Ebay) bolted unistrut to it, and then have some u-nuts on the panels that line up with the unistrut holes. Some star-knob bolts allow for a quick...

    Victron SmartShunt question

    Correct - the reason for having same length cables is to not introduce different levels of resistance (from cables) that makes one set of batteries have a slightly different dis/charge behavior than the other - which can lead to some batteries working harder than others, and having premature...

    Victron SmartShunt question

    I'm doing the same thing with a modular/portable setup. I have (2) physical battery banks in milk crates (2x 12v Lion UT-1300's in series to make 24v) - each with an SB175 2/0 cable going to my "control" box (Growatt 3000 inverter, breakers, outlets etc). The control box has a pair of SB175's...

    choosing a 24v >=5000w inverter

    @frostyllama - I'm looking at a similar plan as you - though for a portable off-grid system. I eventually want ~5-6kw of power - but often only need less than half that, so planning to go with (2) Multiplus 24v/3000kVa units that can allow me for modularity, and redundancy - combined when I need...

    Advice on dual 3kw (6kw total) system for small concerts?

    Thanks for the feedback. I don't forsee a need for split-phase - though I can see the benefit of running a single large 30a/240v cable to a power distribution center (like the spider-box/temp power ones) closer to the load, rather than multiple 15/20a 120v cables the whole way. This would also...

    Advice on dual 3kw (6kw total) system for small concerts?

    I'm looking to build out a cargo trailer that can provide power primarily for mobile sound/PA systems at festivals and rallies- and looking for any advice on the general concept, design, or equipment options. I'd like to be able to supply around ~6kw at 120v AC. But I'd also like to have...

    Looking for a surface mount for 175amp Anderson Connector

    I have one of those Australia SB175 ones shipped to the US - it was a while back, while international shipping was pricey they sent it. I also have 2 of the SB50 panel mounts I'm not using and would resell in the US if you wanted them. Ditto what someone above said - I'm just through-bolting...

    Best kind of quick-connectors for medium / high amperage loads?

    I use Anderson SB175's for battery->inverter connections. Despite the name - they are UL rated to 280a. I have been using Anderson Power Pole 45's on my panels - but I find they aren't rugged or secure enough for my portable use - but since I switch between parallel/series depending on my...
