I understand net metering, local power company requirements and NEC code related to net metering, but I need to know about the inverter, specifically whether any grid-tied inverter is offered by any manufacturer that can perform straight net metering from a generator to inverter to the power...
Does anyone know of a manufacturer who makes larger inverters (15-20KW) that can use either an AC or DC generator to product power for net metering. Ive searched for days and all I come up with is systems that require solar panels to do the net metering. I'm not trying to power any loads, just...
I have searched the internet and spoken to the manufacturer of my equipment and can not find an answer. I am using RFExplorer (test equipment) to measure the power generated by my ham radio antenna. The only options for displayed power is mV/m or nW/m2. I am trying to find out how to convert...
berkeman,
The mast is support by two 4" x 1/4" thick C-channels embedded in 6000lb of concrete. The C-channels are on each side of the 4" tube and extend up about 6 feet with a bolt at about 5.5' above the concrete running thru the C-channels and tube to act as a fulcrum to raise and lower the...
Let me see if I understand this correctly.
The short side of the fulcrum is 1/5 the total length of the tubes and the long side is 4/5 the total length. If the center of mass weight of the long side of the fulcrum is 865.5lb then it would take a hand winch with the capacity to pull 5 times the...
I know the weight specified was based on just the 4" tube but ultimately it will also have the 3" tube. I appreciate the help! It helps quite a bit. I believe my hand winch is rated at 2500lb, so it should be adequate to raise and lower both tubes.
This is for an antenna. The fulcrum is 5 foot from the bottom of the tube and the fulcrum is 5-1/2 foot about the ground. It has no counter-balance weight except for the 5 foot after the fulcrum. I am not concerned with the added weight of the antenna right now because I will over-size the hand...
how do I calculate how much force is needed to lift a horizontal metal tube to a vertical position. The metal tube is 25 feet long, weighs 300lb and and pivots 5 foot from the bottom. I will be using a hand winch and the cable attaches at the bottom of the 5 foot end of the tube.
