Monocrystalline 3kw Off Grid Solar System MPPT Off Grid Power System

Complete 3kw 48vdc 220vac Off Grid Solar Power System Independent Electricity

Description

Off Grid Solar Power System uses solar panels to convert sunlight into electricity, and then enters the solar charge/discharge control cabinet to charge the battery pack (lead-acid battery/li-iron phosphate battery) through the sink box, and finally the solar off grid inverter power supply is used to supply power to the user load through the AC output distribution box, which runs independently of the national grid. Off Grid Solar Power System can also be used in conjunction with generators/utility power/constitute a multi-energy complementary power generation system to supply power to the load.

Features

• Type: Off Grid Solar Power System

• The use of high-quality military-grade components to ensure product stability

• Power generation statistics function, can view daily, monthly, and total power generation

• Sixth-generation high-efficiency IPM intelligent module, efficient and stable performance, with strong protection functions, short-circuit, overload, over-temperature protection safer and more reliable, the service life of up to 15 years or more.

• Intelligent, modular design simple structure for easy maintenance.

• Dual mode startup selection function, through the LCD setting can set two ways of buck startup and frequency startup. This can give full play to the power of the inverter, no longer need to expand the capacity of the inverter when with motor, inductive load, saving the user money.

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

• Type: Off Grid Solar Power System

• Areas without electricity such as mountainous and pastoral areas, border guard posts, communication base stations, island power supply, or areas with inconvenient and high electricity costs

• Household solar power supply: used in remote areas without electricity such as plateaus, islands, pastoral areas, border guard posts and other military and civilian life electricity, such as lighting, TV, recorder, etc.

• Household lamps and lanterns power supply: such as garden lights, street lights, portable lights, camping lights, hiking lights, fishing lights, black lights, rubber cutting lights, energy-saving lamps, etc.

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 FairylandSolar^TM 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 CASISOLAR^TM 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.
