    Small expansion to generation capability...

    Externet: To answer your question, you would have to provide a bit more info on your current system. But in general, it sounds like you don't want to mess with it, or risk screwing up something that is working fine. That being said, I might be in a similar position, and here are my current...

    Samlex now has a split-phase inverter charger

    This looks like a very capable inverter. I spent about 30 minutes looking at the extremely detailed manual, and did not see any mention of stacking. What did jump out at me is the very high DC input range at 68v, and that it is listed. Nice! Maybe Victron will take note, and get some of...

    High Voltage Inverter / MPPT Solar Charge Controller

    It is Tabuchi. Battery Hookup has typos they have never fixed. Very high quality inverters, and they can be bought for a LOT less than what BH is charging. There are a lot of them sitting in warehouses being neglected since Tabuchi shut down their San Jose office.

    Are there any high voltage (300-400VDC) mppt controllers?

    ponobill could you make a SolarEdge work in this scenario? They purchased Kokam and are bring one of those packs to market, at about $6k for a kw pack, high voltage. I wonder if some clever person here can make another high voltage battery work with the SolarEdge inverters? Also, just check...

    Victron Multiplus II 2x120 - Too Loud?

    JC1409: Instead of the Multiplus 2, you could consider the older series units Multiplus or Quattro, which have a thicker case. It would cost more, but might not be as susceptible to noise transmitted through the case itself. Just speculating...no real world experience to back that statement...

    Building a 72KwH battery system, help understanding these Li-ion modules.

    You will get many opinions on this forum to consider before making an informed choice. It is wise to do what you are doing right now...ask questions. Just a couple of observations to add to the list: There is nothing wrong with Battery Hookup. Like you said, they don't hide what they are...

    36v inverter for SAMSUNG 8S 28.8v 7.8ah 225wh w/ BMS

    The whole point of those packs is that they have a working BMS. If you are not able to parallel them up in sufficient quantity to meet your load demands, why even bother? Snoobler is right. The OP has 8 packs, so a couple hundred dollars total. Why spend much bigger money on an oddball...

    Security System for Off Grid Container(s) & Shed

    Get good insurance. Take lots of pictures, and store them somewhere safe. As a victim of a large burglary, I can tell you that next to nothing will stop a determined thief. Cordless Sawzalls, portable torches, hydraulic jacks for spreading jambs...the list goes on. Do what you can, but get...

    Offset Electric Boiler energy usage with batteries and solar?

    Mechdriver: I prefer chocolate/raisin/oatmeal...thank you. The electric boiler would be a big mistake. Two years ago, I swapped out one that my friend had running just to heat his work shop. His electric bills went down an average of $150/month when running that boiler. Here in the Midwest...

    ~100kwh for 24/7 off grid home

    Tanoshimini: How are your 16s cells faring? I'm still looking for the right solution for my prismatic cells, which if left unchanged would be 8s/16s. Also have some 12s I might want to modify to get that voltage up. I need to understand, and verify what happens with the voltage curve and...

    Offset Electric Boiler energy usage with batteries and solar?

    mechdriver: you suffer the same affliction that I tend to exhibit at times. You see a technology you like, and then want to find reasons to justify it. Nothing wrong with that, if it makes you happy, and you end up getting what you want as a result. I've done most of the things you are...

    16s Chevy Volt 64v battery BMS and Inverter.

    Snoobler: Did you finish up this battery, and if so, how is it working? I'm very interested in your thoughts on the subject of charging 16s to a lower voltage threshold. About a year or so ago I read a very detailed Samsung white paper on the topic of NMC batteries, but for the life of me I...

    Schneider xw pro 6848 not powering up with eg4 lithium battery

    Nope, they don't make these, or even assemble them. They just unload containers of them, shipped from China.
