Output
is about 12 amp-hours per day. This will run a couple of
12 volt lights, a 12 volt black and white TV, cassette player,
radio and other small appliances.

2 × 250 amp-hour, 6 volt batteries
1 × distribution box
1 × 12A regulator
1 × 200 watt inverter
Output is about 47 amp-hours per day. This is a good system
for typical home use. It gives almost three times the power
of the previous one and means more time to run appliances
or more storage to cope with prolonged overcast periods.
The 200-watt inverter is large enough for a TV and video.

2 × 350 amp-hour, 6 volt batteries
1 × distribution box
1 × 20A regulator
1 × 350 watt sine wave inverter
Output is about 94 amp-hours per day. This
is an ideal starting system for remote home owners. The
inverter option lets you use small AC appliances up to 350
watts continuous such as TV, video stereo, blender and drill..
A sine wave inverter is ideal for sound systems and variable
speed equipment.

Out
put is about 141 amp-hours per day. with the batteries and
solar array in a 12 volt configuration or 70.5 amp-hours
per day if setup as a 24 volt system. With the 24volt system
you would need to pair the solar panels so that you have
three pairs of solar panels. This system will run DC appliances
including a 12 V or 24 V (compressor motor type) refrigerator
and pressure pump, as well as AC appliances such as an energy
efficient 240 volt automatic washing machine, vacuum cleaner,
power tools etc. Any system larger than this should incorporate
a battery bank of 24 volt or higher.

This system will supply loads up to
2.8 kWh per day which may include all standard household
appliances with a maximum surge loading of 6.5 kW.
With
all the above systems you may run extra low
voltage (ie 12 V or 24V) or 240 volt
equipment where a suitable inverter is installed. Refer
to the typical appliance ratings on get and idea of what
can be run on an inverter of a given power rating.
