2kw off grid solar system Configuration

Off-Grid Solar Systems

An off-grid solar system (off-the-grid, standalone) is the obvious alternative to one that is grid-tied. For homeowners that have access to the grid, off-grid solar systems are usually out of question.Here`s why: To ensure access to electricity at all times, off-grid solar systems require battery storage and a backup generator (if you live off-the-grid). On top of this, a battery bank typically needs to be replaced after 15 years. Batteries are complicated, expensiveand decrease overall system efficiency.

Off-grid photovoltaic power generation system is widely used in remote mountainous areas, areas without power, islands, communication base stations and street lamps and other applications.Photovoltaic phalanx converts solar energy into electric energy under the condition of light, and supplies power to the load through the solar charge-discharge controller, and meanwhile charges the battery pack.In the absence of light, through the solar charge and discharge controller by the battery group to dc load power supply, at the same time the battery also directly to the independent inverter power supply, through the independent inverter inverter invert into alternating current, to ac load power supply.

Half Cell Module comprises two separated and identical solalr cell arrays, which means the ordinary strings of cells are cut into

halves, and these shorter strings compose which has separated current paths. When a module is shaded, only one side shaded array's

current will be impacted, while the other array will still be functionally producing power. Under this circumstance, when a module

is shaded, the affected working areas of Blade will be 50% less.

By cutting solar cell into halves, the internal power loss will be lower and hot spot effect will also be reduced.

The working principle of the grid-connected and off-grid integrated machine is that when the grid is normal, the inverter switches to grid-connected power generation mode, and the photovoltaic power is converted into MPPT mode.

Feed power to the grid. When the grid is abnormal, the inverter will swing to perform anti-islanding detection. Switch from the need to switch to off-grid power generation mode. Although the grid is abnormal, the inverter continues to invert photovoltaic power into high-quality AC power to the load. powered by. In this way, it is possible to prevent the shortcomings that normal power generation cannot be performed even though the photovoltaic is normal due to the abnormality of the grid in the stand-alone grid-connected mode.

Longer Cycle Life : Offers up to 20 times longer cycle life and five times longer float/calendar life than lead acid battery ,

helping to minimize replacement cost and reduce total cost of ownership

Lighter Weight : About 40% of the weight of a comparable lead acid battery . A " drop in" replacement for lead acid batteries

Higher Power : Delivers twice power of lead acid battery ,even high discharge rate, while maintaining high energy capacity

Wider Temperature Range : -20ºC~60ºC

Superior Safety: Lithium Iron Phosphate chemistry eleminates the risk of explosion or combustion due to high impact overcharging

or short circuit situation
