Product Details
Complete 3kw 48vdc 220vac Off Grid Solar Power System Solar Kit
Home Use
Description
Off grid solar power systems are widely used in areas without
electricity, power instability, islands, communication base
stations and inconvenient wiring for street lights or monitoring
systems. The utility-complementary Off Grid Solar Power System can
realize the working mode of mixed utility and solar power supply,
in which solar power takes priority and can automatically switch to
utility power when the solar power supply is insufficient, with
almost zero switching, without affecting the load.

Design of Off Grid Solar Power System
- According to the load size and type, single-phase 220V or
three-phase 380V, the rated power of off grid inverter is
determined.
- According to the discharge time of the energy storage battery
required by the load, determine the size of the energy storage
battery (such as how many kwh to store).
- According to the load power consumption (how many kilowatt hours of
electricity) and the local sunshine situation, select the board
with high power.
- The size of charge controller is selected according to the size of
photovoltaic panel and battery voltage.
- Supports, cables, etc. (installed on the roof or floor).
Application

station, fiber optic cable maintenance station,
broadcasting/communication/paging power supply system; rural
carrier phone PV system, small communication machine, soldier GPS
power supply, etc.
Oil, marine, meteorological field: solar power system for cathodic
protection of oil pipelines and reservoir gates, living and
emergency power supply for oil drilling platforms, marine detection
equipment, meteorological/hydrological observation equipment, etc.
Company Profile
Together with our customers and suppliers, we have been partners in
solar battery industry for 12 years and have supplied over 20 kinds
of patent solar systems for home and abroad.
In 2008, we established FairylandSolarTM and won our first solar home system project--“GoldSun” project for
whole Shaanxi province which was a famous big project appointed by
Chinese government. During 3 years installation, we were always
moved a lot when people showed true smile when lighting their home.
They should carry a heavy battery and walk hours home, so
aftersales is so difficult that pushes us to supply high quality
products with long lifetime. We invested gel battery production
line with a 50 staff team who has 20 years production experience
for AGM battery. For the enough good quality and reasonable price,
we becomes a stable supplier for solar projects, OEM for them.
In 2018, as the rapid development of lithium battery, we
established CASISOLARTM that started a team only for packing lithium batteries. During the
past 3years, we found the wide difference between price and
products. As government promotes “ giving retied battery a second
life” , some make a profit in troubled situation, providing retired
cells for solar making great lost in a long term or even has
personal safety hazard.
So in CASISOLAR, we don’t think it is 100% safe to use retired
battery cells. We only accept cells at Great A with 5 years more
warranty. We didn’t grow up quickly but we harvest every customer
we have cooperated. We always enjoy and appreciate troubles met
during every cooperation, and give great enthusiasm and confidence.
Our mission is to provide solar energy at low cost over a long
lifetime.
