GridFree inverter with Limiter with output power 900W works with input voltage range 22 - 60 Vdc. The limiter can reduce output power according to actual consumption of the house. MPPT function provides max. possible efficiency of solar panels.

 

Product description

The SUN 1000 VA grid tied inverters with limiter (GTIL) work on their AC output only with the support of el. 230V grid. PV panels or a battery in the appropriate voltage range can be connected to the DC input of the inverter. An internal limiter for power overflows to the grid is included. All necessary data and parameters can be monitored and set on the built-in display.

The SUN 1000 inverter with the external accessories listed in the documentation meets the requirements for parallel connection to the Czech grid (RfG).

The most common use is to reduce self-consumption from the distribution network by connecting the inverter anywhere between the distribution network and the point of consumption (Figure 1)



In the case of using a battery and a limiter, the energy obtained from the sun can be used even when it is not shining. If the energy produced is not enough for the current consumption, the remaining part is automatically replenished from the grid. Without a limiter, the system can operate into the distribution grid as a generating plant (PV plant) in surplus power sales mode (Figure 2)

Inverters can also be used to increase the available power in island (off grid) systems, e.g. in combination with Victron island inverters, in AC coupling mode (pairing with the AC output of the island inverter instead of the distribution grid).

Application - Single-phase or three-phase system with battery and limiter



Due to the possible accumulation, it is particularly suitable for the use of all generated electricity for own consumption.


Application - AC coupling with hybrid or island inverter



If an AC mains independent inverter is designed for AC coupling (e.g. VE Multiplus), it is possible to connect the SUN inverter with limiter to its AC output. Its output thus does not affect the Multiplus' own mode (AC battery charging), but the overall output power is boosted. The output of the SUN inverter in AC coupling must be less than the output of the island to which it is connected. Charging the battery via the AC path through the Multiplus (from its input or output side) is only possible after the addition of other protection or communication elements or functions and their correct setting.


Application - RFG compliance



GF-SUN-1000G2, GF-SUN-2000G2-T, GF-SUN-1000G2H and GF-SUN-2000G2 products with additional accessories meet the requirements of the Commission Regulation EU 2016/631 (RfG NC).

(Requirements can be specified according to regional distribution grids)



The interruption of power supply from the production module is ensured by contactor KM1, which is switched by connecting the N wire to its coil from the distributor control device. Connecting the N wire switches on the contactor and disconnects the production module from the distribution network via its power NC contact.

The delayed connection of the production module after a mains failure is ensured by the time relay KA1. After a loss of mains voltage, the relay KA1 galvanically disconnects the production module from the distribution network (breakdown point KM1). When the voltage is restored, relay KA1 reconnects the production module after a set time.
