    My Growatt has been switching between 50hz on battery and 60hz grid for months - what devices have I ruined or potential damages?

    Off grid system , and it was set to 60hz Reset twice before. Unless US intermittently switches to 50hz while I’m charging.

    A Strange Issue that occurred on my Ecoflow Delta Pro and the 10 second fix.

    This fix is in the faq section of the app. I found it by accident when my pro and extra battery stopped staying in sync chargewise. Took 2 complete cycles. I use 80 to 20% in normal operation.

    My Growatt has been switching between 50hz on battery and 60hz grid for months - what devices have I ruined or potential damages?

    Mine has done this a few times now. At first I thought it was my fault because I had changed some settings. i noticed my air purifier and central heating fan makes a different noise. Sure enough 50hz, I haven’t made any changes in months.

    I just don’t have the skillset…. So, how “easy” are solar generator systems??

    Sure why not have 4 12 volt batteries when one can have one 48 volt battery, as an example. YouTube videos showing builds on hand trucks with one 48 volt battery, all in one inverter and electrical connections are nice. They are easily scalable by connecting additional batteries in a stationary...

    If you do EBay Ecoflow and EBay are selling refurbished Delta Pros and other equipment with full warranties at good prices. I bought several items and they are perfect condition. No company will I know will warranty customer errors that blows up their product, if you exceed specs, even with...

    I just don’t have the skillset…. So, how “easy” are solar generator systems??

    Reality is some people just need for fix problems with a check, my brother is that way, brilliant at his job, plenty people are. Some have interesting life experiences by not admitting it upfront. Power stations like the Delta Pro and others with LifePro4 batteries were built for you. Press...

    Mpp or Growatt?

    My 48v 3K Growatt has settings for bulk,absorp,float plus other options for starting stopping charging and switchover. You should talk to a marine knowledgable distributor. Wiring, bonding requirements, and shore power connections etc. are different in that world.

    Using Roofing Tin as EMP shield

    Just got Ecoflow Delta PRO, can I use external LiFePO4 batteries to add capacity??

    A power supply isn’t a 48v battery, power supply is fused and can’t deliver massive amps, solar panels are fused by most. Everything is fine until it isn’t.

    Just got Ecoflow Delta PRO, can I use external LiFePO4 batteries to add capacity??

    The YouTube videos I’ve seen used scooter batteries or DIY 18650’s. Has anyone connected a LiPo4 48 volt 100AH battery like this? if I do this with my Delta Pro I’m going to use a 10 amp fuse in case it doesn’t go as planned. Even though the fuse likely wouldn’t blow quick enough to protect...

    Idea to safely charge inverter capacitors

    That has not been my experience with several Growatts, and a handful of 48 volt inverters. Few hours or less disconnected lets the genie out.

    Idea to safely charge inverter capacitors

    I built this for my small 48V system after having my Growatt disconnected for a couple of hours and forgot the precharge. Still can't find my cat ? https://diysolarforum.com/resources/inverter-disconnect-switch-with-precharge.60/

    EG4 48v 25a Battery Charger Update

    Not sure what's going on but I received an email from you guys today. This line popped out at me. Is this a store credit or an actual refund going forward? "We would like to offer a credit to your customer account for the difference in price + $50.00 for the inconvenience."

    EG4 48v 25a Battery Charger Update

    I purchased my 25 amp charger early November 2021. It was an 17 amp charger from the beginning. Glad the company is stepping up, I'm going to keep mine, probably won't even deal with getting a partial refund. All this depends on the warranty situation for those who choose to keep them. It sounds...

    Safe Grid Use of the 5000ES and transformer

    His brief comment in that video was, use an internal transformer all in one. Don’t use external solutions. Distributors, and some YouTube creators are realizing the liability box they have placed themselves in. Companies like Growatt have no business selling products, that can easily kill...

    Schneider xw pro 6848 not powering up with eg4 lithium battery

    This Li-ion guide Appendix has different start up routines for Schneider approved batteries. Interesting info if you haven't read it. The minimum number of batteries to support inrush current vs battery sizes is interesting. Also have you tried removing data cables from your pack long shot but...

    Eg4 48 volt battery charger

    Are you changing all neccessary settings on your Schneider when you swap back and forth between the two types of batteries? Have you verified the correct settings with their tech? I just read the manual and it's not uhh, lay customer friendly as compared to MPP and Growatt. The multiple...

    Growatt 3000TL LVM-ES limit AC Input?

    Yes it is, when I asked Ian about having this same problem, changing those settings fixed my charging problem and tripping breaker. Do you own a Growatt 3000 ES?

    Growatt 3000TL LVM-ES limit AC Input?

    Have you tried playing around with setting 2, also the battery not charging is controlled by setting 12. Set that the voltage you want the batteries to start charging in line mode.

    Eg4 48 volt battery charger

    That's disappointing to hear, I purchased that 25 Amp charger last month for same scenario, wanted to switch to Anderson connector. I called the company and asked if doing that would void the warranty. The answer was no, changing out the clips wouldn't. Fortunately mine is charging fine on my...
