I like these 'grounding bars' used inside the circuit breaker boxes but have not found a proper mounting method inside a plastic box yet...

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...

Checks as fitting the wishes, thanks !

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 ?

o_O To bring down 40V panel to 13.8 V battery. Or, to bring down 36V battery series to 12V lights. The 12V lights in the image take 1.2 Amperes each. Will check for a charge controller that can accept a big 40V panel.

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...

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...

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...

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...

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. You have all my attention, Brett. In a farm, with no internet, no WiFi, no router, will your solution work attaching a laptop to a data cable plugged to read the Growatt inverter performance and history ? Or, as smart phone has its own WiFi / bluetooth implemented; can it link the Growatt...

Thanks. Not being able to see the reports of my own equipment. :poop: Not being able to see how it works in a farm without fu...n internet for miles around ? :poop: ...Common garbage business tactic. :poop: Not fixing the display bugs... :poop:

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.

Would be much better reusing the plastics, but agreed, is against the law to bury in a landfill the idiots that misdispose plastics...

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...

Thanks. Am not after finding the optimal angle. Just curious to compare flat to my 15 degree roof tilt.

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...

Fixed. Reset the "Show people's signatures" that somehow deselected. Thanks, gentlemen.

Hiding the signature ? Others see it ! But I do not. :oops:

Thanks. I do not have any local network. PC hardwired-plugged to internet and nothing else.

Thanks. No dark mode, never seen nor been at the forum from a mobile, ever. :oops: Screenshot, now :

Hi. Did some moderator remove my signature ?

Thanks. Hmmm.... In doubt from its description if that one counts energy. Confused me, perhaps only counts power. The sure thing is I do not want the web involved.

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...

Hi. The RS485 adapter arrived in today's mail; it is wired now pins 3&4 to the USB plug adapter and am ready for idiot-proof instructions for a dummy. Sorry, has to be hand-helding instructions, when god created the computer idiots I was first carrying the flag... I have a Linux, a Chromebook...

Thanks, 50woodie. Sent a direct message to you. Are the '5 boards' all the same 'capacitor board' or the complete set in the SolarCity inverter ?

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...

Under $1K for a ~3.5KW inverter only.

Thanks. The 'Solar assistant' website shows Growatt a not banned inverter. Is anyone using that application for a Growatt instead of the manufacturer server ? Pasted from the Solar Assistant website : ================================================ Step 2 - Is it listed as NOT supported...

Thanks. Under $1K. The 'so many options' part I do not understand. Are they abundant in the market ? Examples please ? I do not want a chinese inverter manufacturer conditioning the intrusion into my compfuser for the system to show me reports and work properly and pushing me to have...

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...
