This is the DC connection area of the inverter Should connect +1.1 , 1.2 ,1.3 and negative 1.1 , 1.2 ,1.3 and then measure polarity and voltage of each?

So should I go with hybrid inverter with battery backup? Still connected to the grid for Net Metering

you are right I have 10AWG wire . The Fronius creator report tells me String fuses required String combiner/Y-connector required

The wires going to the inverter are extensions with MC4 connectors at the roof panel side-not connected right now That is what I will do in a bit . Connect the 6 wire + ground to the inverter connect MC4 to the extensions Verify that the voltage and polarity at the inverter connections are...

Thanks for the answer. Should I consider a hybrid inverter in case I do not make the deadline of 31 December when Net Metering expires in Illinois? Also I got quotes for 10kw and 15kw or should go with 20kw? It will be installed on flat roof with non-penetrable ballasted bracket system

Hello I need someone who can design a one line diagram . thanks

Should first attach the PV wires to the inverter and then connect to panels? or Should I connect the PV wires to the panels and then attach to the inverter and then measure polarity ? 13 x 3 panels series DC voltage 700VDC 10 Amp - 3 strings 6 wires + ground wire I do not want the wires to...

Please explain and what is the best option for the 3 strings to be connected should all be on the same MMPT?

Hi what diameter conduit should use for 3 strings from panels to inverter? 1 inch or 1 1/2 inch . Also should use metal or PVC conduit and what kind of junction box? thanks

this is from the Fronius inverter manual "Multi MPP Tracker inverters have two independent DC inputs (MPP Tracker). These inputs can be connected to a number of different modules. Each MPP Tracker has 3 DC+ terminals. There are a total of six DC- terminals. 3 Connecting two–six strings in...

Can anyone suggest a combiner box for 3 strings -39 panels 13 panels per string . Also for the panels extensions that are outside exposed should use different PV wire than the THHN that goes in the conduit. Thanks

Thanks what type of 10AWG wire did you use ? Hi can you explain the wires in the junction box? are there 3 strings?

Thanks I am also looking to get the home depot 10 AWG wire. Is this parallel wiring?

I have Fronius Symo 15kw 208V 3 phase . Has a built in DC disconnect Input Data Number of MPP trackers 1 Recommended PV Power (kWp) 12,0 - 19,5 kWp Max. usable input current 50 A Max. usable input current total (MPPT1 + MPPT2) 50 A Max. array short circuit current (1.5 * Imax) 75 A...

If connect the PV wires to the inverters while disconnected from panels After connected to inverter - plug the MC4 to the panels to measure voltage and Amps built in DC disconnect at inverter Off and AC Off

Hi I have 39 x 415W panels arranged in 3x 13 panels 3 strings . I have a Fronius Symo 3 phase 15 kw inverter. What type of combiner box DC do I need for the 3 strings . Any suggestions . thanks

I have 39 panels and I will have 3 strings (13 panels per string ) is THHN 10 AWG wire good for conduit us? Also is your junction box in the picture closed to the inverter or on the roof? thanks

wire size 10AWG

solved

thanks I will

yes https://www.fronius.com/en-us/usa/solar-energy/installers-partners/technical-data/all-products/inverters/fronius-symo/fronius-symo-15-0-3-208 TRINA SOLAR TSM-415NE09RC.05 415W

Hi thanks . Are the numbers corresponding to 10AWG the number of strand wire? 1 inch IMC Conduit392918

Do you install one fireraptor RSD on 2 panels? I have 415 W panels I have a Fronius Symo 15kw 208V 3 phase inverter

Thanks Does Galvanized Steel Electrical Conduit For EMT works for outdoor ? also what junction box is suitable thanks

Thanks ! Does Galvanized Steel Electrical Conduit For EMT works for outdoor ? also what junction box is suitable thanks

Hi how many panels should use with Fronius Symo 15kw 3 phase 208V? Fronius Solar Creator says between 12.33 kWp and 17.5 kWp while the Technical Data says Recommended PV Power (kWp) 12,0 - 19,5 kWp

Hi I am working to use Fronius 15kw 3 phase 208v with an input PV between 12kw and 17.5kw. Yah I was offered your setup with 3 single phase inverters to run 3 phase inverters. But since I have 3 phase from the grid and this will be grid tied the power company recommended to use 3 phase...

Has anyone bough or use ZNShine 455W ZXM7-SHDB 120 Cell Bifacial from ussolarsupplier.com? Any feedback welcomed

I need some help finding and installing rapid shutdown to the solar panels. I am looking at FireRaptor , Tigo and APsmart Anyone has experience installing and using any of these? Any help is welcome. Thanks

yes you are right

Do you think bifacial will radiate heat on a flat roof flush mount 5 inches from the roof? Also do you have any gain on your setup? thanks

The inverter has built in manual disconnect and is in off position. No RSD

I am planning to order a DIY kit 20kw 3 phase 36 panels 575W with 20kw 3 phase Growat inverter from China. I applied to the power company for Net Metering and interconnection Did not apply yet for city permit in Illinois. This is a self-install -will hire an electrician for interconnection I...

Hi here id the Fronius Symo creator report. I need some feedback on wire size -if 10 AWG will work Also the report says needs String fuses required String combiner/Y-connector required What type of combiner box should use?

Has anyone had experience with or installed a solar stack mounting system? I am considering the use of solar stack system on an asphalt flat roof to avoid the additional weight that comes with ballasted mounting systems. Thanks

Did they install one at each panel? What inverter do you have-is it connected to the inverter? Can the Ap smart be installed independently with stop button I understand what Tigo and APsmart use the same technology I have a Fronius Symo 15kw 208V 3 phase the only model that does not have...

I understand what Tigo and APsmart use the same technology I have a Fronius Symo 15kw 208V 3 phase the only model that does not have SunSpec PLC or Rapid Shutdown communication I am planning on installing myself

My inverter is Fronius Symo 15 kw 208 V 3 phase model did not have the RDS option. Any way I can add to the 39 panels an RDS system later on? Right now all the panels are connected in series in 3 rows of 13 panels The wires going to the inverter are extensions with MC4 connectors at the roof...

Hello here is the inverter report - I have a spool of 10 AWG wire and one red from home depot Cerrowire 500 ft. 10 Gauge Red Stranded Copper THHN Wire

I also have a red home depot 10 AWG wire -will tis work or I should return it https://www.homedepot.com/p/Cerrowire-500-ft-10-Gauge-Red-Stranded-Copper-THHN-Wire-112-3873J/202304724

Thanks . can you recommend a suitable combiner box that will work withe the 3 strings ? I am looking at the 4 in 2 out but not sure about voltage Amp
