So you
want to set your rig up the solar but you are not sure what the size of setup
you need?this is blog is designed to give you the tool needed to able to work
out exactly what are you drawing from your rig' s batteries and what are type
of solar set up you need.
How to
work out watts
The
large solar panel will collect more and more energy less time, but just how big
does the solar panel need be?
A power
consumption of appliance is usually gives in watts. The calculate energy you
will use over the time, just multiply power consumption by the hour of the use
. For the example:
10 what
device use over 3 hour equal 10×3= 30 watt.
How
to we convert Amps to watts
A
energy in watts is equals to the electric charge in a Amps time the voltage in
the volts
Watts=
Amps × volts
The
find electric charge in Amps when the energy consumption is the 300 watt and
voltage is the 240 vollts.
300
watts/ 240 volts = 1.25 Amps.
The
solar panel are commonly used to charge a battery-not to charge a device
directly. There are a couples of reasons for the having batteries . This solar
panels ais should not be generate sufficient watts to the directly power
a appliance, and can build up a higher wattage via an battery. Secondly the
battery can regulate this Power goins in the appliance at constant rates.
Battery
capacity is a measured in Amps hours( eg.120 Ah) you are need to a
convert this to watt hours by the multiplying the ah figure by the battery
voltages ( eg. 12 v) see the calculations above
Ah
refers to Amps hours. Rating are usually found on deep cycle battery . If in a
battery is rated at a 100 AMps hours it is should delived 5 Amps of a power for
a 20 hour or 20 amps of a power for a 5 hours.

120
Watts/18v= 6.6 Amps .
The
power is inverter convert is your storage's battery power into a the 240 volts
AC that runs your appliances. Unless you only Run 12 volt DC applianceyou are
will need a power of inverter to supply your AC.
There
are two type of inverters
The
modified sine wave & Pure sine wave
The
modified sine wave used is to be considered adult power but the some aren' s s
bad they are used to be, you can use this inverter type for a things that don't
have sensitive electronics 4 example fridges, cookers pumps you are may have to
be careful Ved some appliance search s laptops and TV so check first.
The
charge controller/ regulators
You can
use charge controller from above 50 watt solar panels. Charge
controller/regulator is a necessary to protect the batteries from overcharging
and supply them with the proper amount of energy e to promote a Long
battery life. If the charge it regulated it can have a damaging effect on the
battery being charging.
