    Share your success

    Here is a snapshot of my power bill over the last two years. Share your success with your off grid(ish) systems. System was commissioned in August and making full power Sep 1 of 2023.

    Eg4 6000EX help

    Are you running in voltage mode for lead acid or do you have the BMS hooked up and properly reporting the SOC?

    Off-Grid F150 Lightning Charging

    I know @Will Prowse already did an F150 video quite some time ago. I think there have been some updates since then (hopefully). I bought one a few weeks ago and I wanted to share my setup. I am using an MPP-8048 and 11.4kw autotransformer (completely disconnected from grid) to function as an...

    Rack Mounted Battery enclosure to vent failed cells

    I am thinking I might start with this ductboard. Any reason not to use this material? https://www.homedepot.com/p/Master-Flow-48-in-x-120-in-Duct-Board-R-6-DBOARD1/202974245 Maybe these fans for intake and exhaust...

    Rack Mounted Battery enclosure to vent failed cells

    I think it's mostly about air exchange rates. One of my stacks of batteries sit in a 3k sqft shop, so I am not sure that venting the whole room is a great idea. We are just trying to prevent the buildup of the gases to dangerous levels. I would think we would have many things to consider for it...

    EG4 6500ex and 6000ex flickering lights and firmware

    My lights flicker with my LF inverters and my HF inverters.. Many makes and models.. Seems to me that it's more tied to the loads connected to the inverter than anything else. For instance my lights don't flicker at all when my freeze dryer is shut off - the moment it's turned on - the...

    Wow, basen rack.mounts batteries destroy a home in germany

    I am not trying to be rude, I just don't want to jack this thread with off-topic things. @houseofancients shared some valuable information for all of us and I don't want to step on it by any means. Hence the link to the other thread.

    Rack Mounted Battery enclosure to vent failed cells

    I agree, an enclosure will lead to a more predicable result. Anything that will trap and move dangerous gases to the outside is worth the conversation to protect against this failure mode. The biggest question is how can we also not freeze our batteries when it's 0 outside? Do we have a detector...

    Wow, basen rack.mounts batteries destroy a home in germany

    So who wants to help me design a cover that goes around your batteries that will vent outside? Seems to me like a reasonable mitigation to prevent this failure mode. While the propensity for failure seems to be relatively low, the risk is complete destruction of your domicile. Thread is here...

    Rack Mounted Battery enclosure to vent failed cells

    I think in light of recent news about the explosion in Germany, having a discussion on risk mitigation methods is prudent. I think designing an enclosure that goes around the battery packs that would vent directly outside is worth discussing. My initial thoughts are to make a direct vent...

    Wow, basen rack.mounts batteries destroy a home in germany

    The concentration of gases would be highest inside the battery case, so it makes little sense to me that there appears to be no damage to the battery case at all. Something that would ignite with this kind of force would seemingly show at least some evidence damage at the source. I would say...

    Finally finished my RV

    It's a heartland fuel. They probably aren't much different though.

    Finally finished my RV

    No, and I am not 100% sure I should. It would be a lot of work on my rig
