1000W Solar Grid Tie Inverter w/ Limiter MPPT Pure Sine Wave DC22-60V to 110VAC
Solar Grid Tie inverter MPPT Pure Sine Wave 1000W with Limiter DC22-60V New upgraded firmware Version 5.1 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 New upgraded firmware Version 5.1 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 . Introduction Why we produced the GTI-L — 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 GTIL .The first generation GTIL must be used with an additional limiter module,we also add an switch button to enable the inverter either can work at limit mode or at normal grid tie mode. 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.
