Then I turned the heat pump on, it started fine. I do have an easy start on it Mine is setup for no grid...

    OUCH, panels still hurt on a cloudy day

    I have been swapping panels around, taking the 330w 60v Panasonic panels over to the new home to install and replacing with 315w 40v Hyundai until we move out of here. Anyway, I flipped the breaker off for that string and went about my work. I noticed one of the paralleling Y was water damaged...

    FPL installing EV chargers in Florida

    I noticed these being installed a few weeks ago, apparently they are up and running now. They are in a quieter part of town rather off the beaten path, odd location.

    3 year old system. SolarEdge SE10000H-US HD-Wave Inverter with 45 P400 optimizers. Worked great when I removed it, I have the production details with a login to the system.

    I have two of these inverters for sale, one is brand new never used, was a replacement for the other one that has a short circuit on the DC bus.

    Felicity solar BMS for sale

    I could not get these BMS to send their data to anything other than EDMS software so not much good for monitoring, I ended up swapping them out for JBD BMS hence have these for sale now. As a BMS they are extremely good, they just don't like talking. All four were working when pulled and I have...

    Swap JK or JBD contactor BMS for regular JBD bms

    I am trying to parallel multiple battery packs and read the data from all of them. I managed to grab five JBD BMS but cannot use either a JK or JBD with the contactor. Therefore I'm wondering if anyone has the opposite problem of me and would like to swap equivalent BMS. I am in central East...

    July 17 Solar flare event

    I just happened to be in HA changing some settings when I noticed my panels were producing more than they are rated for, I thought I had buggered up a setting. But no, checking on SA I am seeing the same large peaks. Some could be cloud edging but there was indeed a solar flare event during this...

    Cool down the garage but don't throw that energy away.

    So in my Florida garage I have my hot water tank and a beer fridge plus three inverters and six batteries. At 9:00 a.m. this morning my garage was at 90 degrees Fahrenheit and my beer fridge and inverters are showing signs of stress. I had thought about putting in a mini split but decided to go...

    Electric dryer power reduction ???

    I had mentioned in another thread that I thought it should be possible to reduce the power consumption in half by half wave rectifying the power to the heating element. I bought a 200A diode pack and installed it today and can confirm that the initial test says it can be done. I will continue to...

    So just how sturdy are the LV/SP6548.

    Well let me tell you my experience. I started with solar to mainly run my HVAC to offset the cost here in hot and sunny Florida. Started with Growatt 6000T that worked quite well but it occasionally (maybe once per month) could not start my year old Carrier regular heat pump system. It would...

    HA high PV voltage input warning ?

    Hello all, Anyone know how to setup a simple warning when the PV voltage input is above a threshold ? I am noticing the PV voltage is getting up there on my Solark on cold mornings. A simple email/text or even a red/green lamp on the dashboard would do the trick. Cheers.

    Watch out for bus bar shorts to battery case

    I made up a new battery pack using EVE 280ah cells and used the supplied bus bars. However, I like to attach the BMS leads directly to the bus bar with a screw. The bus bars I got were flat and my self tapping screws slightly too long, I noticed a small spark when screwing down a lead from the...

    LV6548/SP6548/6500EX-48 etc control panel heat ?

    Has anyone else noticed how hot the control panel gets on these units, especially around the RJ45 ports ? Has that always been the case with older production runs or is it something new ? I opened up a display and immediately saw what is causing this, a linear 7805 voltage regulator. I measured...

    Another source for battery/inverter cable terminals

    I was in NAPA the other day and happened to see that they had a good selection of crimp on ring terminals. They were very heavy duty and they had a large assortment of sizes.

    Does VOC reduce with age ?

    I have a cheap AIO unit to play with and it's max Voc input is 75v. Can I use panels with say Voc of 38 2s2p here in sunny Florida without the likelihood of blowing the input on the AIO ?

    Separate charge and inverters or AIO ?

    What is the best in terms of long term reliability and ease of use and repair/replace to run a whole home offline ? I can handle wiring anything up and configuring settings. Also why would you cobble together a battery system when the pre built packs seem to end up the same price ? I want...
