Doc, I looked up that EVE 280 Ah cell and it said it was a M4 screw. So are you going to drill out for a M5 Helicoil?
Amazon has this kit:

Good luck man, you have to fix it, if you don't you will be tried and found...
I total get it now. At my day job we communicate with hundreds of sensors using our 475 HART Communicator.
“HART” is an acronym for Highway Addressable Remote Transducer. The HART Protocol makes uses Frequency Shift Keying (FSK) standard to superimpose digital communication signals at a low...
Yes Korishan, they transmit on the DC line some FSK signal.. This reference design interfaces an AFE031 Powerline Communications Analog Front End with a C2000™ MCU to send and receive data over a wired coupled interface using frequency shift keying (FSK). The design demonstrates the SunSpec®...
What I have learned from a long boring APsmart video is the receiver operates on voltages from 7.7 volts up. They call the the signal from the transmitter to the receiver the "Keep Alive" Signal. The device switching mechanism be it contacts or solid state can switch 550 watts what ever your...
Here is one brand

No extra wires to run, just plug the device in parallel with your solar panel. To close the relay they must be using the DC from the solar panel. I'm gonna search some youtube videos to get the fine details. If my theory is right then at night the array will be all disconnected as the sun come...
The way they want the code satisfied is, a transmitter transmits on the DC line of your Solar array (negative or positive line it does not make a difference) a signal to receivers on ever solar panel that control a relay that close when the transmitter is on. This transmitter is ran off your...
Tough code they want the power off within 1 foot of the Solar Panels. I drove around the neighborhood and I see shiny stainless steel disconnects with big red handles. And now they said those are from 2014 Code and we can't do it now. Power must be off before the firefighter hit the roof.
You made sense cak, if I was a firefighter here is some common sense I would use. I’m not cutting through any metal pipe running across anybody roof with an axe be it electrical, water or gas. I guess I‘m too real world as I do things and not engineer concept things. So if I put 10 solar panels...
Ha! I wish I was getting that model actually the 14 I have to get are:
APSYSTEMS, RSD-D-15, PV MODULE RAPID SHUTDOWN COMPLIANCE SOLUTIONS
Model: RSD-D-15
Manufactured by: APSystems
Condition: New
Estimated Delivery: May 13th - May 19th
In Stock
Price: $56.91
I researched the solution to comply with NEC 690.12 It will cost me $50 per panel plus $60 for a transmitter. I have to do this on my 14 Panel system. There is a box with a contactor that you plug your MC-4 plugs into . There is a transmitter that runs on ac that has like a current transformer...
You good OGITC, I think this only applies to new installs. The city not going to drive around looking this roof-top solar violation. There is no money in it for them, only the manufacturers of the so call "Rapid Shutdown Devices". But then again if these manufactures line the city pockets with...

I get it, we don't want to hurt our Firefighters trying to put out a fire on our house that have solar panels but I looked at some commercial devices and their price
and I said "here we go again". And to make matters worst...
Man! Utility Companies have all the lame excuses, the backfeeding into the grid issue has been addressed and still continues to be address way back when the Grid-tie inverter was being developed.
Good article. Often we view Republicans are for big business but Gov. Ron DeSantis used his head and decided on what was right. Here is my theory, if 3/4 of a state have solar then the Power company would make less money, Period. But they would burn less fossil fuel, so their fuel bill will go...
Roger, all the cells you have has a milliamp-hour (mAh) capacity rating. From my limited cell experience the lowest I have dealt with is 1500 mAh cell. So all the same that cell will output 1.5 amps for 1 hour at the nominal voltage of 3.6 volts. Find what your cells mAh capacity is. Here on...
