I have a 4000 sq ft home, and I diy self installed 9.8kw panels on the roof (Solaredge7600) and 5.6kw panels on the ground (Solark 15k) as well as 20kwh Pytes batteries. I have three 2 ton AC units in different zones. I want to install three Microair soft starts, but I also want to know if...

I am planning to buy four pytes v5 batteries to add to my solark 15k during the black Friday deals. They do not have a server rack, but I am thinking of just buying a server rack and putting the batteries inside. My question has to do with how to wire the lynx power in. I am planning for...

I am trying to put eighteen panels in a row landscape format using the power field plastic buckets. I have a rarely used dilapidated tennis court where I want to put them along the long 120 foot fence wall. I asked power field for a ballast design, and they first recommended 16000 pounds of...

Am planning to get a solark 15k to feed one of my two 200amp panels. Most of my critical loads are in the one panel. I recently installed iotawatt to track energy usage. See picture below. In the evenings I consume a lot of energy with three AC units. I can see the peak here getting near 15k...

My utility room contains my natural gas boiler which is part of a whole house hydronic system -- hot water tank and hot water is piped to each of the air handlers (three of them). It is a great heating system, but it means the boiler room is very hot. In the same room is located my two main...

I finished installing diy a grid tie 7.6kw solaredge used system with 40amp back feed breaker and 9.8kw pv. With the help of this forum, I received PTO in April 2023. Now, I want to install a solark 15k so that I can add more pv to the system and batteries and have backup should the grid go...

My understanding of the PV world is that there used to be a standard size for residential of <50 pounds and approximately 39" x 65". Back in the old days, there were incremental increases in efficiency and so panel wattage went from 200 watt to 210 to 220 to 240 to 260 to 280, etc. Then panel...

Does anybody know if I can install a different size Solaredge inverter in parallel to my existing SE7600H-US. My current system is 7.6kw, but somebody is selling a 10kw HD wave inverter near me, and I am wondering if I can install them in parallel (with communication of course to set them as...

It seems that Sol Ark and EG4 all use 48V nominal batteries for energy storage. I was watching an interesting youtube video where someone was able to connect a Nissan leaf battery to a Fronius inverter, because the Fronius inverter allows for more range in the battery voltage. I am...

I have been bitten by the solar bug. Starting with 4 panels on my shed in September 2022, I have completed installation of Grid Tie Solaredge 7.6kw inverter, and am enjoying the harvesting of free energy! I am now thinking about my next project, and I am thinking about how to convert ICE...

I have about 320 Sq feet of space on a small flat roof that is southwest facing with no trees. I want to add ten solar panels maybe using unirac rm5 to this epdm rubber roof surface. It is slightly pitched. I tried to design this with unirac builder, but they are hesitant to approve something...

These panels are not currently in use. I am storing for planned future use, but it is amazing to see the difference between 0 degrees and 80 degrees. My panels on the roof at 23 degrees are probably closer to zero! Can't wait for PTO and I can turn on the system and then go clean them

Just curious. I paid the ahj a small fee for construction permit. I paid the ahj a small fee for electrical permit. Solar panel electrical inspector is coming tomorrow and said I can pay him $300 cash or check tomorrow. Does that sound right? I also need the Township inspector to come out...

I want to build a four panel ground mount like seen here. Except... I don't want a huge piece of concrete. Instead, I am envisioning concrete for the post tie in, but I want to supplement weight with pavers. This way, it is more manageable if I want to move it. I am only planning four panels...

Does every EMT need to have a grounding lock nut? This AC disconnect was repurposed from a prior solar installation, and I see one grounding locknut where the AC was going to the inverter. My 8AWG is coming from 40amp from main electrical panel to the AC disconnect. Do I have to connect the...

Will this be acceptable by the inspector? I am in PA. We had no snow this year. I could so dig away the berm to move it lower as it is a pretty serious slope

I am about to start my grid tied, permit approved solar panel installation on my roof. I want to buy wire, but I just realized I am not sure whether I am supposed to get solid or stranded THHN. My design is PV wire to soladeck to 50 feet of 3/4" EMT to Solaredge 7.6kw inverter. I am planning...

Sorry for the newbie question, but I want to route my DC PV wires through the roof eave via EMT conduit. I will not have a solar panel over the plumbing stack seen in these two pictures, and so I want to put the Soladeck near the eave of the roof, and then bring the 3/4" EMT conduit directly...

I bought a used system which included the racking material -- Unirac SFM Infinity microrails/rail-less sytem. I can re-use this in my 7.6kW roof, but I want to be able to overpanel and ultimately add extra panels at the ridge. However, in order to do this, I really need to start my panels as...

I bought a used system including optimizers, panels, inverter, etc. The prior owner says it was working, but before I install the panels on the roof, is there a way to know that the inverter is working before I set everything up? I could set up five panels with optimizers and then wire into...

Someone is selling green 10awg thhn 500ft rolls for a good price. If I need black and red x2, and thus different colors and then ground 8awg, can I buy these green 10awg for residential pv wire inside 3/4 inch emt? I would put correct color red and black at the junctions (soladeck on roof and...

I am new to solar, but I did get a used Solaredge system with 34 panels and inverter and optimizers. I am confused by the AC input/output to the solaredge. I am planning to backfeed a 40amp circuit to my 200amp main electrical panel. I am planning to have the Solaredge inverter in the...

I spoke with a solar salesman today and sent pictures of my electric panel and meter. Basically I told them I have 2 x 200amp panels. However they noted that I only have a meter for 200amp service. I only use 15000kwh a year which fits 200amp service rather than 400amp, but they did recommend...

I need the wisdom of the group. I have a 24V 100Ah battery Battleborn LiFePo4 charged by solar 1.1kW. In the summer, I want to run an electric pool vacuum cleaner 180watts. I want to create a low voltage DC disconnect. I am new to this, and I have no electrical background. I am thinking I...

I am planning to have a local company install solar on part of my roof. I am planning on getting the solark 15k, so that I can add more panels via DC inputs myself later. They will pull permits and install the first 12kwatt roof panels. One question I have is whether I can back feed into a pool...

I purchased a sunrun installed solaredge system that was removed from a roof. 9.5kwatts into a 7.6 kw solaredge inverter. It came with a racking system I do not recognize. It has black four foot bottom rails and then many many small silver pieces as shown. I am more accustomed to two long...

I just spoke with the Solarark sales person in Texas, and he just said that a SolarEdge DC optimizer system with Solaredge inverter could send its AC output to the "generator" AC side input of the Solark, so that the Solark serves as the controller. This would allow me to use the Solark...

I am just a hobbyist and started on my solar journey with a small shed project with 4 x 280watt panels and 2 x 12vx100Ah batteries and Victron equipment. I started this just two months ago, and I am hooked. Well, I wasn't looking for this big a purchase, but somebody was selling these for a...

i have this plan to run my 24v 1500 watt inverter to a 100 amp circuit panel. I know that I only have three wires and thus only half the panel will be active and thus only single pole circuit breakers will work, but I am hoping with more and more panels will one day allow me to provide more amps...

I have a Cotek 24v pure sine wave inverter which does have a remote switch (looks like telephone jack cable). I want to employ a low voltage disconnect to protect the battery, but I read that I have to shut off the inverter and not shut off the battery. It looks like I could use this remote...

Now that winter is on its way, I wanted to build a battery box to keep some insulation. I build a three sided 2x4 box to house my heated battleborn lifepo4 batteries. I decided to run my circular saw directly from the battery and experienced some challenges starting the saw. I think it is a...

I am considering placing solar panels on the tennis court lights shown here -- kind of like what is done on the electrical utility poles. Can I run the wires in PVC conduit at the top of the chain link fence. There is already electric line obviously running to the lights, and so I don't want...

I posted this in the beginners section but got no responses. I am building this out right now and want to be sure I did not skip something 1120 watts of used panels in 2S2P (72v/16amps) to a solar disconnect then to a victron blue solar 100/30 for a 24v battery system (I know that 1120/24=46...

1120 watts of used panels in 2S2P (72v/16amps) to a solar disconnect then to a victron blue solar 100/30 for a 24v battery system (I know that 1120/24=46 amps, but I have used panels and expect poor sunshine on my shed as it only gets sun from 9am to 1:30pm) Mppt goes to the red and black bus...

This is such a small issue, but what is the best way for me to get the pv wires from the shed roof in to the side of the shed. I drilled a small home and put the wires without a conduit. Should I use pvc pipe? Is there a simple answer?
