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'...

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 ?

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...

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...

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...

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 ?

Greetings. At my residence; all my solar grid-tied generation fed into the grid gets 100% credit for the same electric rate consumed from the electric utility, and will be that good for 22 more years... they said... Now the law has changed to the generated energy to be credited at 75% of the...

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...

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...

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 ?

Hello all. An inverter that inputs solar panels, no battery, and household 240VAC as output but does not feed energy into the grid ? That is, household consumes its generation during daylight and consumes from grid at dark. Or, an inverter that 'stops' from feeding into the grid any generated...

Greetings. When I first installed my system, before the electric company replaced the energy meter with a Net type; my old 'disc' meter ran backwards. Had to stop generation to avoid having a next reading lesser than the previous reading. Is there types of non-Net meters that do that or all go...

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...

Greetings. My house has the plain standard circuitry InverterOUT------------SafetyDisconnect------------30Abreaker-----------AllHouseLoadsHere-----------MainBreaker--------------EnergyMeter-------------UtilityPole The 30A feedback breaker protects the wiring between the main panel load rails...

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...

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...

Hello all . To shut off the inverter, page 86 of its manual shows to - First turn off the DC switch, - Second turn off the back-feed circuit breaker at the house panel If later, I want to turn the system on again; page 85 shows to - First turn on the back feed circuit breaker at the house...

Hi. AFCI --- Arc Fault Circuit Interrupters. Are they a typical feature built-in in inverters ? Do you know which ? What protection against arcing do you use; what is the norm to avoid chained failures and burn the house ?

Hi. Seen several models of that brand but need to make sure the MIN 3000 TL-XE is not a model for split phase (USA) and can work in Europe. Does it have a phase and neutral AC output only ? Do you know of a link that tells all ?

Hello all. If in a neighborhood there is several grid-tied inverters providing energy to the grid; then the utility has a fault and loses power; will all the inverters cease to provide their generation ? Is it possible for some inverters to misinterpret the faulted grid as if it was still...

Hi. Did some moderator remove my signature ?

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. Say you own a big utility company that generates electricity from hydroelectric, diesel, whatever and serves the whole town... There is all the normal overhead as employees, trucks, maintenance equipment, all typical... selling energy at a rate of $0.10 per KWh There is someone in town...

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...

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 ?

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 ?

Good day to all. A 'normal' array of panels producing -say 400VDC / 10 A- series interconnected with MC4 connectors. (Upper image) Say the wiring has branches and besides the MC4s, resistors can be attached in-circuit in those branches as pictured below. (Lower image) Resistors installed in...

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 ?

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 <----------->...
