SOURCE: I am installing an RS3000 inverter in my RV.

Please remove the belt off the altanator then turn the key on if the altanator spins with the key on in the run postion then yo have a bad diode trio in the altanator, if that checks out them you need to test all wall scokets unplug the refrigerator and see if you get the fault code also unplug the lights one at a time to see you get a fault code. the most common problem would be the florsent bulbs. hope this helps.

Why would I have a reading of pgrid na on my solax inverter.

It looks to me that the Power Grid is not connected to the inverter. Some inverters are intended to feed the grid, and if that is not detected, it will not produce power. If you want an inverter to work as an AC power source when the grid fails, then what you have purchased is the incorrect unit.

Sloar inverter is saying grid fault what should I do

most inverters will not work unless there is grid voltage ( utility power supply) to turn the inverter on
if it is saying grid fault that indicates a power line in problem and no external power supply
contact your power company as there could be a black out in your area or maintenance work being done
if not the case call an electrician

How many 12v batteries are needed to run a 15000w inverter properly

It is normal to use only half of the capacity of a battery and this is called 50% depth of discharge (DOD) so the watts of a battery is volt X amp hours eg a 12 volt bat @ 200 AH would be 2400 watts but you can only use half of that other wise the battery will be stuffed, so all you have is 1200 watts, if you have a 400 AH battery you would have 2400 watts, you also have to know the capacity of the battery and this is call the C rating of the battery once you have that you can work out how many hours it will run for.
On an of grid system I would not use any less than 6oo to 700 AH @ C100
It is normal to size the batters to energy demand in KWHrs per day of (AC load )
Hope this help.

I have solar panels that put out a little more voltage then they are rated at,and they keep faulting out my grid tie inverter.I need a resister to knock down the voltage about 8 volts, got any ideas?

I like to ask, is the voltage from the solar panel messure with some load connected or is open circuit, normally solar panels produce high voltage than the working system, the reasson for that is to have Amperes in of to charge the batery, these is related to the size and power generated by the panel.
No need a resistor or in any case use a voltage regulator to prevent over charge.

My inverter seems to be producing too high a voltage when solar input increases, causing the system to shut down and re-cycle many times during the day. I do not see fluctuations in the grid voltage wwhen...

yes there is a voltage regulator of an electronic kind .
I suggest the inverter is well ventilated( if not) and not positioned in direct sun light and shaded as inverters do get quite hot their function better when kept cooler

I notice my lcd brightness has reduce now this is 2 years old this problem remains same on Dynamic picture mode as well i have check this by connect to a pc and to a DVD using HDMI port...

First of all check the back light setting of your tv. you can see it on the picture setting menu.
Just check when you adjust the back light setting, is there is any change. if it changes and still not attaining the needed brightness level, then you have to check the back light inverter and the CCfL( cold cathode fluorescent lamp) used as back light. if there is no change in the black light, then the logic board or the inverter have some problem.
you have to check the inverter first is it getting the correct voltage from the power supply normally 24v.
if the voltage is ok , then u can do only one thing replace the inverter board to check whether the lamb have any problem. in normal case the inverter will become faulty. lamp fault is rare.

check all these. If you need further assistance fell free to contact me through fixya.

Vx 2245wm "almost" Black screen

craigcorbin, Could be "switch-mode-power-supply"/CCFL "INVERTER" supply that is flakey or better still has a "thermal" problem. Thermal problems arise from temperature cycling of the parts on the circuit board that heat-up due to their need to dissapate energy in the form of heat, and then return to room temp when unit is turned off. Hot = expand, cold=contract After enough cycles occur on an already poorly soldered connection you will end up with a Thermally Intermittant connection which will only get worse due to oxidation of the now exposed RAW METALS to the surounding atmosphere. Sombody will need to open unit and inspect the board(s) for this type of fault. 12fixlouie

U Line CLR60 Ice Maker gets stuck in harvest mode & melts ice

have you got the equipment to change this solenoid valve? you will need a vacuum pump to evacuate the system once you have changed the valve, and the equipment to charge the system with refrigerant (gas).

Panasonic Microwave NN-A770S getting hot on right side externally

If you described this to Panasonic very carefully, and they said it's normal, then I would say keep using it until such time that you get other symptoms. The inverter has some parts mounted on a large chunk of aluminum called a heat sink. It draws the heat out of the parts and the heat radiates and/or convects away. This keeps the circuit parts from overheating. As long as you have good air flow through the vents, it sounds okay.
