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...

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 ?

Good day. If you have a spare ~40V/10A/400W solar panel leftover, how would you implement night lighting around your house, fully independent standalone from the house electricals ? Charge three 12V lead-acid car batteries in series plus a DC-DC converter to make 12V to feed lights ? A...

Hello. What inverter brands/models can report their history and live performance direct to my nearby smart phone without any internet intervention ?

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...

Hi. What to fear or consider ? Say the inverter is next to the clothesdryer in a dwelling basement. The dryer is typically used at night; when the inverter is asleep. Using the larger than needed dryer wiring and breaker as inverter-towards-utility backfeed (in parallel to the 240VAC...

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. Came across with this article that am rejecting... ----> https://www.bbc.com/news/science-environment-65602519 But it is good to see all points of view and sides of everything... There will be some simpler and efficient recovery methods in the future for a panel that has yielded 25 years...

Hello all. When solar panels are mounted flat horizontal, zero angle tilt, as soon as the sun rises until sunset, there is direct illumination of panels. at a very poor angle, but direct exposure at any/every day of the year. Say there is 15 hours of direct exposure in summer. When panels...

Hello. My solar panels feed a 7 series string to MPPT1 input and 7 series string to MPPT2 input. Is it important to keep that same balance ? Can three more panels I have as spares be added in series to one of the MPPT inputs for a 10 series and a 7 series ? Those extra panels to be added...

Hi. Did some moderator remove my signature ?

Hello all. Begging your expertise explained in language for a novice : This Growatt MIN 6000 TL-X COM1 port on the bottom panel ; how do I connect pins 3 & 4 to a laptop ? With something like this RS485-to-USB adapter ? Cannot find in the inverter manual the use for that port other...

Good day. I may be building a small house soon and would like to implement a solar hybrid inverter that can input a string of panels or batteries to output about 3500W split phase 60Hz. I want the unit to report to my computer or smart phone the real time and accumulated performance DIRECTLY...

Hi. A plain system : Solar panels------------>DCswitch--------------DC>Inverter>AC------------->breaker------------->Meter------------->Utility pole When sunny, to shut-off the system; if DC switch is turned off first, arcing at the DC switch may occur. When sunny, to shut off the system...

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...

Hi. Did not foresee this; just noticed now but could be interesting to keep in mind this factor for new installations around my latitude of ~38° N I use electric heating at home, with no other energy source as gas. Installing/commissioning a solar system in -say September- leaves only a...

Hello. Does anyone have this animal ? ----> https://quotes.solarproof.com.au/wp-content/uploads/2014/07/growatt-shine-vision-datasheet.pdf Does it need Internet and router to see reports ?

Hello. Where to buy a Growatt "ShineLanBox" in USA ? What is the difference with Shinelink - X and Shine RF stick - X and Shine WiFi-X and Shine WiFi-F ; ShineMaster ; Growatt WL-BT ; Shine web box ?

Good day. Have a grid-tied Growatt MIN 6000 TL-X. Never used its dongle for reading performance reports or whatever it does as there is no WiFi nor internet provider at the inverter location. Is there a way that dongle can talk to my smart phone directly (I know it has WiFi) , and my Android...

Good day. The single front panel button in my Growatt inverter shows a flaw, and probably all of them do. Touching once is supposed to go one step to next screen. From sleep state, jumps two steps missing the 'current power' display, landing in 'day energy' I was going to tamper with its...

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...

Hello all. A 6000WAC rated inverter with a limit of 550VDC / 12.5ADC input already connected to 2 strings of seven 400WDCout , about 260VDCout / 2800WDCout per MPPT. To add panels in series; do I watch more for the Vin or the Win ? In other words; the current-in is still 10ADC even adding more...

Hello. If an inverter readout shows is putting out -say5KW- into a split phase 240VAC backfed breaker; is it safe to say both branches of the AC are getting equal currents ? With the exception of a refrigerator being on one branch and a television on another, is safe to say each of the AC...

Hello all. What are the numerous capacitors inside inverters for ? Are they in the DC input circuitry to smooth insolation variations or there is another reason ? Or are they in the AC section to supply current during demand surges from sudden equipment starting ?

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...

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...

Hi. Did not see a 'wanted' section. Please delete or move if improper to post here. When these H6 inverters let the smoke leak, some of its guts are seen sold. The board/section that explodes the most, the 'capacitor' board is usually discarded and not offered for sale. Well, that is the...

Hi. When starting a thread, similar titles appear to be evaluated as if already discussed. How to find the same list after the thread is done posting ?

Good day to all. On a very snowy cold day, an 'arc' warning came on and the inverter stopped its normal work. First time it happens to my 9 month old system. Turning all off for 24 hours did not cure it; had to restart and manually clear the fault. When arcing is detected and protection...
