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

Complete 3000watt 48vdc 220vac Off Grid Solar System Independent Electricity Commercial

Description

An Off Grid Solar System is not connected to the electricity grid and therefore requires battery storage. Off Grid Solar 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. The utility-complementary Off Grid Solar 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.

Parameters

Solar panel features

• With high efficiency polycrystalline / monocrystalline silicon chip, power generation is more stable and low attenuation

• The use of anti ash and easy to clean coated glass has high power generation efficiency in the later stage

Solar inverter features

• Full power output, patented product, low no-load loss (low no-load current), high inverter conversion rate

• Compared with high frequency inverter, it is more suitable for dynamic loads such as refrigerator, washing machine and air conditioner, and greatly reduces the failure rate of the machine and has a longer service life

• Optional battery type

Solar charge controller features

• Advanced MPPT tracking algorithm, tracking efficiency as high as 99%, compared with the ordinary PWM algorithm, power generation efficiency can be improved by about 20%
• LCD graphic display of photovoltaic power generation data, simulation of power generation process
• A variety of load working modes can be set to adapt to different working situations

Solar batteries features

• Colloid use status: the sealed reaction efficiency is more than 99.9%
• Small self discharge electrode
• Low water loss rate
• Super long service life

Solar panel bracket features

• Less installation parts, high pre installation in the factory, no cutting or drilling on site, no welding, greatly reducing the installation time on site

• The installation mode of the battery panel is flexible, and the horizontal and vertical rows can be easily realized

• The whole system is made of aluminum alloy, stainless steel accessories and hot-dip galvanized steel, which has outstanding anti corrosion and anti rust ability for outdoor use

PV combiner box features

• Outdoor rainproof design

• Reduce the connection line between PV module and inverter, facilitate maintenance, reduce cost, improve safety and reliability

• High voltage fuse protection and counterattack protection are added to single channel photovoltaic array

Solar cable features

• The wiring of the whole system has pre-processing interface, installation only need fool type plug and screw, no need to buy spare parts

• At the same time, it greatly improves the conductivity and reduces the line loss

• Dedicated PV adapter, waterproof grade IP67

Main advantages:

• Type: Off Grid Solar System

• Five protection functions of under voltage/short circuit/over voltage/over load/over temperature

• LCD intelligent display

• Automatic conversion, automatic recovery and unattended functions

• Wide range of system application

• Full installation technical guidance

• 3 years warranty, lifetime after-sales service

Features

• Type: Off Grid Solar System

• High efficiency MPPT charging mode, three-stage charging control

• Perfect system protection functions include: overcharge, over discharge, overload, short circuit, anti-reverse connection, lightning strike, etc.

• Use imported IGBT/MOSFET as electronic switch, without any mechanical switch

• LCD liquid crystal display system parameters of the current operating status

• New SOC calculation, accurate display of real-time battery capacity

Design of Off Grid Solar 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 System

• Transportation field such as beacon light, traffic/railway signal light, traffic warning/sign light, street light, high altitude obstacle light, highway/railway wireless phone booth, unattended road shift power supply, etc.

• Communication/Communication field: solar unattended microwave relay 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.

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.
