I would think of a alternate source of power for the radio and any critical items incase the bms shuts things down. Just a small battery.

It looks like you could series connect two panels and connect them in parallel with another pair.

You can add a second rod in parallel. Some localities require two.

It would seem that if the manufacturer felt it was important enough to do testing under both conditions and publish those results and include it on the data sheet they should clarify just what is required. Along the same line there must be a proper method of connecting cables or bus bars to the...

I think that in some cases that the location of a disconnect is not considered. If something is going wrong do you want to put your hands near the source of smoke and fire. Another consideration is that the person who is on site may not have knowledge of the system. A disconnecting switch which...

Someone makes a bank of double throw switches so that you can power your devices either from the grid or other sources. The sample I saw had six switches. If you only needed one or two circuits you could use three way switches which are just single pole double throw switches.

Just curious I was reading the thread and wondered about the priority. Did not mean to imply that you or anyone else was ignoring safety.

If you try this you may find out that you can blow a 200 amp fuse before the 20 amp branch circuit breaker trips. Then you can find out that you have shut down a two story office building. Then you can find out how hard it is to find the correct fuse.

Look at San Tan solar before you drive to palmdale

If these packages were not properly labeled how did they get through customs?

There is a product made for the purpose. A reducing washer made for electrical boxes. Assuming that the fitting you have is i/2 inch pipe size look at 1/2 by 3/4 or 1/2 by 1 should not be hard to find

The receptacle just provides contacts so what ever voltage you apply to the terminals it conducts to the sockets. The voltage and current rating is just a convention so that you can provide a power supply which matches the device you are using.

Re the RFI Palomar has a write up on how to cut down on the noise. It is written just for solar systems.

Another reason that the neutral conductor is not fused on a normal 120 volt circuit is if that is the fuse or breaker that opens the circuit is dead in that it will not function but the 120 volt line is still hot a is a danger to a person checking a device which does not function.

To make a estimate of costs you first need to know what the power company is providing. Is this the cost to bring power to the property line with additional costs to extend it to the meter location. I assume they will provide 240 volt but at how many amps, who owns the transformer?

There has been no mention of the calibration of either their the equipment or the devices they are using.

It is required that the area below and in front of a electrical panel has to be clear for safe working access. This applies to anything not just batteries.

I would think that if you look at the manually operated switches you could find something which is not to costly and would be a cleaner solution. In addition to the switching options which have been mentioned there is a mechanical interlock which locks the main off and allows a two pole breaker...

You should consider a fuse close to the alternator. If that cable runs into the body of the RV and it was damaged and shorted to the frame it will shut down the alternator and from there things get worse.

Where did you find the mounting brackets for the panels ?

In the manual they mention a absorb timer but I did not see any way to set it the default is six hours. Are there any error codes on the display on the inverter ? If you have a flooded battery you might try changing the type and see if it will charge a different type.

What is the advantage of 1/2 size cells ? A panel of 72 std cells compared to 144 one half size cells.

It would be a help if there was a sample of how to specify a product. In the case of asking for a cost from a seller in China what items to consider and how to describe them. What you are buying , how it will be paid for, how it will be shipped etc. For a beginner I don't know what I don't know.

It is possible to have a UL field inspection. My experience with this involved electrical equipment which were up dated and the new assembly had not been approved as a assembly. These changes were normally done on a weekend and we would get a inspection from a local person who was retired from...

Go a salvage yard and look for a electrical service entrance section should be about six feet tall. You can get the bus bars and drill your holes as required. Get the standoff insulators while you are there. I would try to find tinned copper but aluminum will work.

For information re ferrite devices you can look at palomar-engineers.ccom

I have two sets of panels one east one west. Is there a advantage in using two SCC so that lesser producing panels don't affect the other set?

Depending on the amps and voltage a normal thermostat like would be used for a household a c unit

Can you connect PV2 to the controller that does not work?

Look up information from Palomar they sell ferrite devices. You want to read their article.
