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 customer’s 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.
Technical Data

Sensor Clamp (ONLY FOR MODEL WITH LIMITER FUNCTION):
How to choose the inverter :
1. About input voltage :
The 22-65V model inverter will start up at 25V, after starting, the inverter can work in 22V-65V .
Vmp 30v-60v Solar panels connected in Parallel suggested, for example : 4 pcs 200-260w (Vmp 31v solar panels in parallel ).
the 45-90V model inverter will start up at 49.5V, after starting, the inverter can work in 45V-90V.
Vmp 50v-90v Solar panels in parallel suggested ; for Vmp 25V-45v solar panels , we suggest 2 panels in series , the total voltage will be 50V-90V , then connect 2 or more groups in parallel . for example : 2 pcs 200-260w (Vmp 31v ) connected in series , 2 groups in parallel . Save 2 connectors .
How to use the grid tie inverter ?
1 unit inverter installation / more units inverters in parallel . the inverter AC output can be connected in the AC plug of grid in the house .
2-1. 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
Work under External limiter mode,
Pls make your setting on the LCD and save it,details setting operation,pls read the GTI manual.
5 Battery Discharge Power Mode
New upgraded firmware enable battery or solar limiter current and power model.
