#### 48v vis-à-vis 12v Terminology

##### Quick - Reference

The following are the approximate easy-reference conversions for a 48v Solar Array, Charge Controller, or Battery Bank's equation to the more familiar 12v Terminology.

The other Charge Controllers are MPPT by the same Manufacturer.

Hands-down, the MPPT appears a better deal for the needs here. Plans are in the making to converting the PWM 150v 60a Charge Controller over to become a Diversion Control Unit for the Wind Generator.

As a quick-fix toward removing oneself from the Grid, if developing a 12v system, simply use automotove fuse boxes salvaged from the Recycling Yard as opposed to the humongous amount of money it will require to succumb to the AC units typically sold at the monopoly stores.

The difference is super-substantial. The difference is hundreds of dollars vs. \$20.00

Both units shown can handle up to 150volts or 60amps (whichever comes first). The center unit is the MPPT and to the right of the MPPT is the PWM, both were used to charge a 48volt Battery Bank and tested mid-2019 for results. The PWM was replaced by another MPPT unit and instantly showed more promising results.

Line testing performed with 8-year old MPPT Controller by Morningstar.

Although not formerly known to me, the Samlex inverter has operated flawlessly for a year or more. The 600-watt unit has been decommissioned for the larger 1500w Samlex pending plans for re-purposing the smaller 600w unit.

Trojan Batteries from Batteries Plus.

Unlike the Duracell Batteries that Batteries Plus is selling, these Trojans are possibly genuine.

These batteries were all elminated (even the Trojans in the background) and replaced with 435ah Trojans x 16.

This 48v 2-Wire Wind generator has 10 blades, and operates using two wires (as opposed to a 3-wire unit)

The unit is silent even under heavy wind conditions. People walk under it not even knowing it's moving and are surprised at how quiet it is.

This is the first silent wind generator I've ever owned. My previous units were extremely annoying (like a rooster can get sometimes...oh by the way, Jack the rooster is dead).

The wind generator is for sale to make way for an upgrade model

Wind Generator in Springfield is able to be easily serviced from the roof.

When the Kubota first arrived, it was under warranty. So I put it to the test by digging more than 75' to install an in-yard hydrant.

I can say this because I'm not a normal person that thinks before doing something and all I have to say is...I can't even kill it.

The water-line that I used is some very thick-walled poly pipe.

Kubota is a no-joke tractor.
