a solar powered service truck - come see how we can work all day with our power tools with sun power

This article will give our readers an idea of what it takes to make a car using solar panels, DC to AC power inverters and battery packs, enabling the use of 120 V appliances and tools when moving and away from any power supply.
Our system is mounted on a four-wheel drive Chevrolet pickup with a practical commercial housing.
Several solar panels are connected together called solar arrays.
We used a 12 v array for our purposes.
In addition, a 24 v array and a 48 V array are usually reserved for residential or commercial buildings.
We will only deal with the 12 V array for this article.
Our service truck has four Kyocera 125 W, 12 V panels on top of our utility housing.
The formula for calculating the number of amps associated with it is that 125 watts are divided by 12 volts = 10.
42 or 41 amps per panel.
Four sets of 68 amps.
To better understand the situation, a large car-type battery charger can output 40 amps.
This is a very high power system that is enough to power our personal travel trailer for about two days.
The next major component of our system is the charging controller.
The power flow of the panel to the charging controller, an Xantrex 40 amp, a three-stage controller that is able to bring the full power to the battery pack when maximum charging is required.
As the battery pack gets closer and closer to full charge, the controller \"gradually decreases\" to a lower charging rate until the bank reaches about 14 volts and then goes into \"floating\" mode, basically only keep the battery charged to 100%.
The batteries used for renewable energy are different from those used to start the vehicle.
Renewable energy batteries have boards that are much thicker than starter batteries and are manufactured for many cyclic discharges and charges.
They also have a much larger capacity than the start-up battery.
We use the Concord solar extender 6 V battery with 4 series in parallel.
This wiring configuration provides a backup power supply of about 440 amps for our battery pack. These are AGM (
Absorbing glass mat)
Sealed and leak-proof batteries, so there is no safety hazard in acid leakage.
The rated power of each battery is 220 amp hours.
However, when the series and parallel wiring configuration is used, the number of hours of 440 amps will eventually be obtained.
To illustrate the power here, keep in mind that most new homes have an input power from a utility company of 200 amps!
Once all of these power supplies are stored in our battery pack, we need to convert them into available AC power supplies.
This is done by our 2500 watt inverter.
The battery pack and inverter are connected via a very large instrument welding cable.
The inverter takes a 12 v dc power supply from the battery pack and converts it to a 120 v ac power supply so that we can use household appliances such as coffee machines, microwave ovens available for our travel trailers, the most important thing is for our service trucks, for all of our power tools.
Our system enables us to work all day on the new construction site, and there is no electricity in the building even without the noise or expense of the generator.
Of course, the battery library will eventually run out, which is why we build such a large battery Library.
The drainage system should not be under 50%.
The lower the discharge rate, the shorter the life expectancy you get from the battery.
Most of our equipment was purchased from Back Woods Solar in Idaho and we found him knowledgeable and cost-effective.
When we had a problem, they also walked an extra mile for us.
The cost of our system is around $4,000.
We provide all the labor.
