    I like these 'grounding bars' used inside the circuit breaker boxes but have not found a proper mounting method inside a plastic box yet...
  • Post in thread: Higher voltage hybrid ?

    Hello. Is there in the market that you know of, any hybrid inverter that will take about 500VDC input from a roof string of panels; and work with 48VDC lead-acid battery bank; outputting ~6KW split phase 240VAC/60Hz with or without grid presence ?
  • Post in thread: Any on-line calculator with bell-power-curve results ?

    Thanks. Am not after finding the optimal angle. Just curious to compare flat to my 15 degree roof tilt.
  • Post in thread: Repairing inverters...

    Thanks to ALL for the opinions. I can repair anything electronics if I learn how it works. It has been my spoon 45 years. A manual teaches how it works, test procedures and diagnostics. When parts are available, much easier. If parts are unobtanium, the resource is replacing modules/boards...
  • Post in thread: Sorry, will not be worse than plastics...

    Alternative is manufacturing the solar panels in a way that the components can be dismantled/separated. I believe the hurdle is the cells are very glued to the front glass and to the rear backing.
  • Post in thread: Microinverters for novice...

    Good day. Is there microinverters that will handle an input of 400+ W at about 40+VDC single panel ? Is there about 400WDC input microinverters that do not have to be hooked to internet in order to commission/work ? Is the Enphase IQ7A operable without internet connection ? A microinverter rated...
  • Post in thread: Looking to buy used parts for Delta/SolarCity H6 grid tied...

    Please let me know if you have a defunct H6 inverter; am after components or the entire board that has large capacitors on it. Yes, that board, the one that explodes. Please do not discard it. :rolleyes: If I can put my phone here, it is 859 2zero2 6ninefour8. If not allowed; please delete...
  • Post in thread: Hot water heater-off grid

    Good day. Visited a friend in Florida last year and found him making a plywood tray with a glass cover taken from a defunct sliding door and he was ready to make a serpent of PVC pipes in it to be painted black, and sealing the tray with silicone to put on his roof. Somehow I convinced him to...
  • Post in thread: SolarCity H6 Stopped Working

    Hi. Check the user manual page 80 for clearing 'other' faults. If recovers functionality, then I would remove some panels for a less than 6KW DC input for peace of mind and evaluate the H6 behavior then.
  • Post in thread: Disabling active grid-tied inverters

    A tiny bit of planning/prevention for next day can shut off the inverter or its circuit breaker from mains by midnight. If you must disconnect PV panels for whatever, do it at night time. I think...
  • Post in thread: Removed the 'signature' ?

    Hiding the signature ? Others see it ! But I do not. :oops:
  • Post in thread: Removed the 'signature' ?

    Fixed. Reset the "Show people's signatures" that somehow deselected. Thanks, gentlemen.
  • Post in thread: The WiFi router fever...

    Greetings. Why manufacturers of inverters believe everyone uses/has/needs/wants WiFi routers ? My inverter cannot report its performance to my smart phone. Growatt customer service is lost in space; if I have the solar system in a barn by the farmlands away from internet providers, I cannot...
  • Post in thread: Stupid question about H6 SolarCity...

    Hello all. Running this H6 grid-tied inverter from photovoltaic panels and injecting its AC output to the grid trough a 30 Amperes circuit breaker. No batteries, all is fine. If instead of the 30A breaker; a tiny isolation plain AC transformer is used just to make the grid parameters 'presence'...
  • Post in thread: Any brands you want to avoid by all means ?

    Hello all. Based on bad experiences, which brands/models of grid-tied inverters you consider unreliable, weak, fragile, not performing, that you would never use again nor get involved with ? Do you believe their price reflect its failure prone characteristics or the price is unrelated to its...
  • Post in thread: Higher voltage hybrid ?

    Checks as fitting the wishes, thanks !
  • Post in thread: Hacking the new Growatt WiFi-F modules

    Spectacular thread, gentlemen. But I understand nothing of your magic :unsure: Is this about obtaining activity reports of real-time and daily/history performance of a Growatt inverter ? If you can pardon my ignorance; need to ask your expertise if it is possible to read real-time performance...
  • Post in thread: Repairing inverters...

    Hi. Perhaps the wrong forum section for the subject; but can be dangerous for many without proper procedures and servicing instructions. Do service manuals exist or are they plainly unobtanium for the many brands / models on the market ? At least; if no schematics are available to the public; do...
  • Post in thread: Heating with DC...

    Running a grid-tied system, all happy. If the grid dies, can the DC from the panels that would be doing then nothing be used to heat a dwelling ? Anyone using that energy with some switch to reroute the DC to heating elements ?
  • Post in thread: Sharing the feed-back breaker with a load, is it that bad ?

    Thanks. My system as in my 'signature' is all good and fine for 2+ years now, feeding the utility with $0 billing from credited energy. The hypothetical question in this thread would be for my next door house that belongs to my daughter; evaluating to put panels in the back yard and using...
  • Post in thread: No mix and no match ?

    Greetings. Have a bunch of ~40 VDC/400W surplus panels. Have an 'automotive' 12VDC input inverter : Cannot be used together. Or can they ? Is my only choice to connect the panels to a series of 3 lead-acid batteries ? Or is a battery charger an option (charge controller?) with about 500VDC...
  • Post in thread: Microinverter into 120VAC single 'phase' ?

    Hello. Do 120VAC output microinverters exist, 'phase branch' and center-tap-neutral as for U.S. ? I have several dormant spare 400W panels, wondering if can be additionally injected into the grid plugging the microinverter output to a plain 120VAC outlet (which is fed by a breaker in the main...
  • Post in thread: sensing current / power / energy direction ?

    Hello all. What instrument or gadget clamp-hooked to the utility incoming 230VAC split phase wires to a house energy meter can indicate or detect if the utility grid is delivering energy to the dwelling or the dwelling solar inverter is injecting energy into the grid ? Utility <----------->...

    Hi all. Just checking... The arcing (spark) length at disconnection of a DC circuit is proportional to the current interrupted, is that right ? The arcing (spark) length at disconnection of a DC circuit is proportional to the voltage interrupted, is that right ? The arcing (spark) length at...
  • Post in thread: Wi-Fi reporting feature...

    Hello, wondering if there is microinverters that report wirelessly performance/production direct to a smart phone WiFi, NO routers involved ! On a barn in the middle of nowhere to the left; its roof with microinverters system producing power to farm equipment... Can it be monitored close...
  • Post in thread: Grid-tied inverter working during a grid shut-down?

    That was my question that got no response about :cry: ----> https://diysolarforum.com/threads/stupid-question-about-h6-solarcity.24592/ Faking a grid presence; from the response above from solar8484, about 'robustness' seems to be key. But cannot understand the 'power' capacity of the GTI. As...
  • Post in thread: Both operation modes...

    Good day. What is the name for inverters that can work off-grid and/or grid-tied ? Is it 'All-in-one' or 'hybrid' or ...? Is there a selector switch to choose operation ? Can you supply a couple of links for well known brands/models that do both modes ?
  • Post in thread: Multiple inverters, different brands on same grid ?

    Hi. Read somewhere that some inverters 'talk' to each other when outputs are paralleled to grid; and there is a limit of how many can be connected. If the inverters are different brands, what happens, if they have no intercommunication, what happens ? Some people sell their inverter that...
