This kind of system is used in places where secondary source of power other than grid supply is needed. power generated. So that any excess energy needed by the load is taken from the grid. On the other hand, any extra from the solar is fed back into the grid thereby turning the energy meter backwards.
1. connect with power net, no battery ,the investment is low.
2. the solar inverter of efficiency can reach up 98%
3. the solar system is Integrate and modular, easy to use and maintain
50KW grid tie solar system is composed by the solar panel, solar Grid tie inverter etc..
1. solar panels
1. SOLAR PANEL
■ Anodized aluminum alloy frame constitutes a practical square structure ,permitting single use or array use.
■ Guarantee 25 years life span.
■ Dust-proof junction box, and ensure the safe and reliable connection.
■ Silver-white aluminum alloy frame, high transmittance toughened glass suede, white tpt substrate
■ Typical parameters:2 solar charge controller
Solar charge controller is one of the most
important components in the solar power
generation system. It will affect the service life of the system directly,
especially the battery’s. In any case,overcharging or over discharging to the battery will shorten its service life.
System Function
l directly connected to the solar panels (do not connect the battery)
MPPT using precise function, APL functions, solar panels automatically adjust to maximum output power, simply connect directly to the solar panel grid inverters, do not need to connect the battery.
l AC 0 angle with high precision auto-detection
AC phase angle of 0 through isolation amplifier and input to the MCU for high-precision detection and analysis, the phase shift rate of only <1%, thus achieving high-precision AC and combining with the phase modulation. output.
l Synchronous High-frequency Modulation
In the course of the grid, usually with the same phase angle and the net (ie, two-phase alternating current total is equal to 0, with the switch to the two AC fusion) and the product is first rectified AC half-frequency AC to 100Hz, Then the machine produces high frequency current in the circuit and semi-100Hz frequency alternating current generated combination, to achieve high-frequency modulation.
l Pure Sine Wave Output
SPWM directly with pure sine wave output.
l Automatic Sensing Function Solar Luminosity
Brightness perception latest computing technology, solar radiation in the solar panel angle for different light intensities produce different current output, using advanced CPU computing the light of their different degrees, can be directly displayed on the LCD , you can visually see the sense of the strength of the sun unit, use more terms.
l Power Automatically Locked (APL)
The current strength of the different fluctuations, we should use the MPPT function, when the MPPT function adjusted to the maximum power point, the product automatically powers locked in maximum power point, the output power is more stable.
l Maximum Power Point Tracking (MPPT)
Current intensity, voltage constantly changes, if there is no power point tracking, then there will be a lot of problems in the past usually adopted a solar controller, this product uses high-precision MPPT computing power, automatic and immediate to solar panels output power adjustment in the maximum output point, in order to achieve a stable output purposes
l Automatically Adapt To Different Load Power Factor
Adapted to any of the power load.
l Constant Current, Constant Power
This product is constant current, constant output power, without any overload, over-current phenomenon.
l Automatically Shut Down When The Power Output Of a Fault
When the city power system planning power outage there is a failure, the inverter will automatically turn off the output.
l Current Limit Protection
This product is constant current, constant output power, without any overload, over-current phenomenon.
l Stack Multiple Machines (in the parallel machine used)
Multiple machines in parallel can be used to achieve a small power inverter in parallel for the power output.
l High-Frequency High Conversion Rate
High frequency converter, the output more efficient.
