there was some discussion of paralleling existing unused wires in a home to double current capacity, in reference to what the OP is "a pair of existing 50A 240V lines that run to the exact spot". I think it would be rare to have two 50amp 240 circuits run to the same place, and it's more likely...

on a separate note, if he did have (2) true 50 amp 240 circuits, what would prevent him from parallel the inverters by not simply not paralleling the input circuits, just connect each inverter to 1 of the existing 50amp circuits on the other side of the basement, just as you would if they were 6...

Ok very helpful, thanks. They are just so cheap I was afraid they are B stock or undesireable for some reason and on clearance.

Is there a standard connector that is better? If someone had to replace mc4s that were bad, does anyone recommend a brand or type of connector?

@webbbn were you referring to 2 separate 50amp 240 circuits, which would have been (4) 50amp breakers? if so, what were these 2 circuits originally installed for?

What about a pan/tilt tracking array mounted to a 35ft telescopic hydraulic piston salvaged from a semi dump trailer that automatically retracts based on windspeed. ROI will vary significantly based on latitude.

I am also seeing $3200 delivered in NH/MA/RI myself. I wish I could fit a 40ft, the extra $1000 for the 40 would pay for itself. I am looking at $1/watt for the panels and the 20ft container, so it pains me to think I could do 60cents/watt for the 40ft.

looks awesome! i like how you hung the 2x6 on your "4x6" beams and attached the fake ends. at first i thought it was slotted. i think that's a better call....

to that point, whatever ballast is deemed adequate for a 24x12 tent in a parking lot should be sufficient for my setup. i'm going to look into that

for a second my math was terrible and I thought they were 500 watt panels. what panels are those? are they bifacial talesuns? your container is white, so i am wondering if there is a bifacial play possible,

my line of thinking was if there is existing unused wires, his home may be older only have 100 amp breakers from the street but that's not even a fair assumption without knowing the size of the home. me incorrectly referring to tandem 100amp breakers from the street as "200 amp service" doesn't...

@42OhmsPA how are you connecting your SRNE and batteries to comms? i was thinking solar assistant on RPI. i am VERY familiar with USB-rs232 converters and RS485-usb converters, but it appears there are several ways to do this and even 2 different busses on the RJ45 battery ports.

GRID sub panel is now live, inverter AC input connected, inverter AC output connected to BAT sub panel. I also had to take care of some other things in that utility area before moving the EG4 battery rack into place, but it's ready for the welding cable to connect the rack. I'll have the...

Awesome tip, thank you. If I can get the price that low it would be welcomed. SS is offering free shipping until end of jan, and the plan for the pergola is specific to a size of panels, so I may not wait to get the project plan moving.

I only have my mind made up that a weighted solution can work, and it's possible to do it from a space perspective with concrete blocks. If you think that task is impossible, that's all you need to say. You have offered nothing constructive for the restrictions I have for the project so stop...

I have 1 but will have 3 of the new srne hyp 5000w series. I have 3 phase power, going to put one on each leg. I am trying to decide if I should parallel 2 of them to get 240v or parrallel 3 of the to make 3 phase. My question is what happens when 1 inverter fails or is shut down? I was...

I guess this applies to inverter failure also. Does a 3-phase setup with 3 inverter tripple the probablity of a single point of failure and actually undermine the idea of have 3 of these for redundancy? Or imagine 3 units parrellel on a single phase. I would expect if 1 died, the other 2 in...

I realize this thread is old. In theory, why (aside from firmware and possible PCB limitations) could 3 inverters working as a 3-phase team with a battery bank not function as a common solution to convert 2-leg grid into a 3-phase output as long as pass-through was disabled? let me get...

Very excited to do the math, but i'm not going to bother on calculating a solution that I can't install.

It was more a joke for only 2 axis matter with solar. Think arctic circle.

For what it's worth, it's naive for anyone to suggest that all ground penetrating solutions are better than any weighted solution. I am quite sure there's plenty of setups with a false sense of security because part of it goes into the ground, as if there's no variation to what the soil...

i do not own the pavement and have to leave everything as i found it. once holes are in the pavement, water get's under, and frost heaves will ruin it. A big part of this design is the ability to dismantle in several years. if this was staying long term, it would be deep concrete tubes in the...

what is a 20x20 "rag"?

I am not talking about a specific brand, I am talking about hypothetical firmware update to off the shelf single phase inverters, where 3 of them are working as a group to produce 3 phase, 2 in pass through, also rectifying thier inputs to provide the 3rd inverter DC to generate the 3rd phase...

That is a great connector to keep in my parts list, thank you. For this I am looking for something 3 conductor (in a cable) and outdoor. This seems too exposed for outdoor. What I am finding is intended for AC and is not calling out any ratings for DC that I can see.

No I was wrong, you have it correct. For some reason I did not think the end of the chainlooped back.

What are thoughts on using receptacles typically used for AC? It's only me that will have access, both receptacles will be atleast 6ft from ground level, and this is temporary as exterior wall will be destroyed in 2 years. No risk of anyone else down the road getting confused. The selection...

same on my 2 batteries, first time i'm charging them. got them in february, so they sat for 2 months but still reported 2/4 LEDs SOC. i dont have time to pull the batteries from the rack right now. is the inspection needed? what would cause a false alarm?

the trailer is an option, but the roof isn't designed to support weight. roof is 7x14 i might be able to bracket from the edges but a used shipping container is my new path.
