  • Post in thread: using 12v devices while maintaining the simplicity of an All-in-one System

    Not sure if you bought yours yet Russ. To buy from Ian directly go here. https://usa-mpp-solar.com/ eBay charges sales tax in my state now too. I got mine with no tax and free shipping!
  • Post in thread: Mpp solar inverter stops connecting pv panels

    I'd try that. The first pic you posted is what my display looks like at dusk just as the voltage drops low enough to stop producing power. It can click on an off for about 10 minutes then the pv array icon disappears completely
  • Post in thread: 48v MPP set up questions

    Could you tell us exactly what those fuses are and what they're protecting? I'm only aware of the 40 amp ac input breaker on the 24v model. I'd like to keep some fuses on hand in case something blows.
  • Post in thread: New GYLL Batteries 24V Version C Communicating with Growatts!

    I received a 24V EG4 LL in late August Early September that had the dual Posts, No LCD and No breaker. It doesn't (didn't) match anything on their website. I also had damage from shipping and contacted them according to their guidelines. I tried numerous times get someone from Signature...
  • Post in thread: Circuit Breaker / Fuse between AC In and Inverter?

    I use a 30 amp ac midnight solar din rail mount fuse in a baby box https://www.altestore.com/store/enclosures-electrical-safety/electrical-enclosures/disconnectload-enclosures/ac-andor-dc/midnite-solar-babybox-4-slot-ac-or-dc-breaker-panel-p4480/...
  • Post in thread: NEC rapid shutdown requirement seems to require optimizers or microinverters for strings over 80v?

    So if I understand correctly, you have the red switch outside, your also have an AC shutoff outside that has your inverter ac output running through it and back to your off grid panel? In addition the 24 volt transformer in the red switch is being fed by the AC running through the AC outside...
  • Post in thread: 5kva mpp solar inverter setup error

    Based on this manual http://www.mppsolar.com/manual/PIP-GE/PIP-GE%20manual%20%28PF1.0%29.pdf It's battery not connected
  • Post in thread: Battery to mpp solar pip 2424lv msd mppt wire , terminal connection?

    Struggling with this myself. The hole appears to be just shy of 3/4 of an inch in diameter. Largest cable that "should" be able to fit in there is 2/0. From Battery cables usa "Outside Diameter of finished 2/0 cable: 0.660 inches (nominal)" which is a little more than 5/8ths but less than 3/4
  • Post in thread: Lion Energy Safari UT 1300 - $699 @ Costco

    Charging question. Lion specs say up to 100 amps max with better lifespan at 45-55 amps. If I have a 6 battery 24 volt pack 2S/3P I'm left with a single positive and negative post for the entire pack. Several previous posts said because the 100 amps was per battery I could increase the amps...
  • Post in thread: Overloading Hybrid unit and Grid Bypass behavior

    I experimented with pushing my 24v Hybrid inverter past it's rated capacity to watch successfully cut over to grid power. At about 102-4% the inverter actually handled the load fine and continued to pull from the batteries. Above that, it did cutover to the grid and both batteries and grid...
  • Post in thread: Problem with growatt split phase

    Your post says input breaker TO the inverters. This is your aC input for charging and by pass? If yes do you have two hot legs (separate circuits) with one going to each inverter?
  • Post in thread: Solar generation proportional to AC load demand?

    These are lv2424s they can push a ton of amperage via the mppt solar charging. There is no limit on throughput the issue is pv generation rises based on load requirements. I'd think that the PV would generate whatever it's capable of and if the loads don't require it then they push it all to the...
  • Post in thread: Discussion on the 2424lv-pip all-in-one Controller option #1 settings

    Schmism is correct in that the settings you're referring to are what is being used to power the loads. The setting you have SBU is what I use and works most predictably. The Sun comes up - loads are powered by sun, exceed the capacity of solar and battery will fill the gap. Oonce the sun goes...
  • Post in thread: New GYLL Batteries 24V Version C Communicating with Growatts!

    yeah - Mine Says EG4 - on the front and top, has dual Posts and No LCD or circuit Breaker. I didn't expect it to have an LCD but I did expect it to have a circuit breaker. It looks just like the OPs pictures but without the LCD One ear was damaged which was really odd as there was no...
  • Post in thread: Solar generation proportional to AC load demand?

    Ok - Follow up to this. The whole system needed to be reset. Everything now seems to be working as expected - panels are now pushing full capacity to cover loads as well as 70amps to charge the batteries. In other words loads on both inverters total 500 watts but the panels are producing 2200...
  • Post in thread: Lion Energy Safari UT Safety Mode is a PAIN

    my other concern with these batteries is that they are a non standard Ah rating at 90 vs 100. I'm running a 24 volt set up and as these are now discountinued I think that limits my ability to add on later. Whats the net result of have series pairs of differing Amp hr ratings? That's a no no...
  • Post in thread: Sizing an array for MPP Solar LV2424

    I seem to recall Ian stating that while vdc max is 145 you need your voltage not to exceed 115 for the mppt controller. Perhaps someone could clarify
  • Post in thread: Best charge profile for MPP Solar LV2424 and Lifepo4? -- Also Triying to decode charge Algorithm

    The settings you posted will work fine although for charge cutoff I'm using 29v instead of full. It's not clear how that feature works anyway. It never gets to 29v and does switch back to battery mode once it considers itself "full". I'm also using 29.2 for bulk voltage vs 28.2. I'm using lion...
  • Post in thread: Sizing an array for MPP Solar LV2424

    Right. I had nearly the exact same question in the thread I started. This is how Ian answered it. http://www.diysolarforum.com/index.php?threads/paneling-for-a-2400kw-pip.1239/
  • Post in thread: Solar generation proportional to AC load demand?

    Powered everything down and back up. There was something wonky in the software going on
  • Post in thread: Solar generation proportional to AC load demand?

    Via the display screens on both inverters
  • Post in thread: Lion Energy Safari UT 1300 - $699 @ Costco

    13.6 is fully charged for a 12 volt lifepo. The 14.6 is the bulk charge voltage (pushing in) as they get full it should throttle back. Once it stops charging these will settle at 13.6 What is your float? It should be set low enough so they don't keep charging as they don't require a float
  • Post in thread: Problem with growatt split phase

    This - If you're running these in Split phase then you need a double pole breaker from your main panel to deliver both phases (two out of phase hots) to the inverters. And of course, it's assumed you programmed these correctly
  • Post in thread: Lion Energy Safari UT Safety Mode is a PAIN

    Bob142- Let be me be more clear with my question as Lion's reply to you above doesn't really explain what will happen- For example I buy 4 90ah batteries now. 2 strings of series connected in parallel at 180ah 24v. If I buy 2 battleborns later can can I add another series connected pair in...
  • Post in thread: AIMS 12/24V Charger in the RED!

    Did you ever get this sorted out? I recently bought one of these. Tested it yesterday and it ran great. I came down today and noticed the ac breaker feeding it's outlet had popped. Ive been unable to get it working since. Red light only. I've removed it from the battery to reset the...
  • Post in thread: Solar generation proportional to AC load demand?

    Batteries are not close to being full. What I'm reading is the PV output screen. When there is a higher load demand the PV output increases. If there is enough sun to produce this additional power why isn't the system always producing it regardless of demand. In the example in my original...
  • Post in thread: Differences in input between shunt and mppt controller

    I'm not entirely clear what that screenshot from your Rover is telling you but reading it from the top it seems like it's showing you the input voltage from the panel and the resulting wattage that it's generating. The middle section is showing you the current capacity of the battery and it's...
  • Post in thread: Sizing an array for MPP Solar LV2424

    One other thing Ian said was "60 to 115V is the operating Solar Panel voltage range 145V is the max before damage occurs. 115V to 145V - No Charging occurs - dead zone " To answer you question - probably 30-40 Feet. I may pick up 4 LG 360 watt panels(1440 watts) off craigs list and run them...
