Why we produced the GRID TIE INVERTER WITH LIMITER ?

It is in response to the overwhelming clamor from our customers for a product that can control the amount of power that the grid tie inverters (GTI) can generate so that the amount of excess power produced by the solar panels are reduced to insignificant levels, if not eliminated --- because in some countries,the producer pays for the excess power it gives to the distribution grid. This is because the electric power meters (the one provided by the electricity provider in the area) are not aware of the direction of power flow. In other words it only adds even if power is exported to the grid, thus, the consumers will be charged for power even if it is given to the grid, and this is the problem

This is the 2nd generation grid tie inverter with limiter.

With the 2nd generation GTIL,we integrated the limit function inside the GTI-We call this internal limiter.In this way,No additional limiter module is needed,reduced customerrsquos cost,more easier for installation.But in case customer install inverter far away from the main circuit breaker,we also enable the 2nd GTIL work with stand-alone limiter,we call this-external limiter.For sure,the inverter can work under normal Grid tie-no limit mode,just set on the nice LCD and save your setting.

New upgraded firmware enable battery or solar limiter current and power model.

User can set the maximum output power of inverter , this can make the inverter work at cooler contition as user want and extend the lifespan of the inverter .

User can set kick in/off voltage of the inverter which can flexible using with battery bank depend on users mind and can prevent battery bank from over discharged .

Technical Data：

1.How to DIY Grid Tie Inverter Solar System？

 

1.3 AC Output.（Surge protection device is recommended）

1.4 Stackable Connection：

The purpose is let small power inverter become high-power inverter.

In order to achieve higher power use requirements, the use of this product can be stacked, such as: 4 grid tie inverter 1000W of stack used is equal to 4000W, and the number of open stacks (No Quantitative Restrictions).

 

2. Using Grid Tie Inverter With Limiter Model

2.1 The Grid Tie Inverter with Limiter delivers only the power needed by the load and prevents delivering excess power hence avoids excess power in going back to the Grid.

2.2 The heart of the Grid Tie Inverter with Limiter is the Limiter Module (LM). The LM continuously sampled the power needed by the load through the current sensor connected after the Main Circuit Breaker. The LM then will process the signal. It then sends signal to Grid Tie Inverter how much power to deliver to the load in real time.

2.3 The user, after installing and connecting the GTIL correctly, need not do anything and the unit will do its work automatically.

3. Installation of GTIL With Internal Limiter

3.1 This installation is not require an additional limiter module,Installation is much easier.Clamp the current sensor cable to the hot wire to measure the current,the internal limiter will auto detect the load power and control the inverter output power,excess power will be well controlled.

3.2 External protective device including dc and ac SPD(Surge protection device),dc and ac breaker,etc is recommended to installed in the system.

4.Limiter Setting on the LCD of the inverter:

The GTIL include three working mode:Work as normal GTI without power limitation.Work under Internal limiter mode and Work under External limiter mode,Pls make your setting on the LCD and save it,details setting operation,pls read the GTI manual.

5.Inverter Display Instruction

5.1 The inverter also integrates with limit function, preventing excess power from going to the public grid. Select "Internal Limiter", the inverter will work under limit mode. The inverter's output power will be determined by load power. For more details about the limit function,

5.2 On this screen, you can select "Bat or solar limit Current Mode," which allows you to limit the DC input current by adjusting the numbers. You also need to set the low protect voltage and reboot voltage. This is very useful for battery discharge.

8.Installing Sunshine Grid Tie Power System to Three Phases Utility Grid.

When the Capacity of Gird Tie Power System is larger, intall all the power system to one

phase of the utility grid is not reasonable, maybe this will cause unbanlance of the three

phase of the utility grid.

In this section, we will explain how to install Sunshine Power System to three phases utility

grid seperately in order to balance the fed power.
