Home Off-Grid 450W Solar Panel System With Battery Backup Price In
1. Production Introduction
Solar power system is mainly used to drive all kinds of household
electrical appliances and office equipment, to solve the power
shortage situation without electricity or people living or working
The household power generation system is generally composed of
photovoltaic square array composed of solar cell modules, solar
charge and discharge controller, battery pack, off-grid inverter,
DC load and AC load.If the output power supply is AC 220V or 110V,
an inverter is also required.The photovoltaic phalanx converts
solar energy into electric energy under the condition of
illumination, and supplies power to the load through the solar
charge and discharge controller, while charging the battery.In the
absence of light, through the solar charge and discharge controller
by the battery group to DC load power supply, while the battery
also directly to the independent inverter power supply, through the
independent inverter into alternating current, AC load power
Off grid solar sytem Controller Optional
Lead-acid Battery Optional
Solar panels optional
Support utility grid and generator voltage input

3.Solar power generation system operating principle
(1) The geographical location of the site.Including: location,
latitude, longitude, altitude, etc.
(2) Meteorological conditions of the installation site.Including:
monthly total solar radiation amount, direct radiation amount (or
sunshine percentage), annual average temperature, the longest
consecutive rainy days, maximum wind speed and hail, snow and other
special meteorological conditions.
(3) Maximum load.
(4) Load electrical characteristics
(5) AC load on the power requirements, AC load in addition to the
need for a larger solar panel, the requirements of the inverter
will also be different due to different loads.

5kw solar system?
The customer thinks that all his load is only 2440W. With a 3KW
system, it is enough. Why use 5kw?
Reason: The customer's home load contains emotional load(air
conditioning), and the starting power must be at least 4 times.
Finally, customers choose to believe in our professionalism and buy
a 5kw off grid home solar energy system.
