250W/300W Solar Grid Tie Power Inverter,optional DC input range 10.8V-30V/14-28V/22-60V,Low cost and easy installation
NTRODUCTION: ‘SGPV’ (Small Grid Tie Photovoltaic System)
The only plug and play small grid tie photovoltaic system
The stackable small grid tie photovoltaic system
ADVANTAGE
There are many advantages of SGPV compare with the traditional grid tie system.
1. Low cost and easy installation -
SGPV can make full use of all types of buildings’ surface that face to
the sun in the city as well as
fast and easy installation of solar modules and grid tie inverter. It's very low maintenance costs.
fast and easy installation of solar modules and grid tie inverter. It's very low maintenance costs.
2. Free combination -
SGPV can be used as a separate grid tie system and can be setup as a
large solar array with many of them. The
quantity of SGPV in the array is just according to your desire. If you are planning to install a grid-tie PV system, in a general way, the
solar array and inverter need to be carefully matched to ensure that the inverter’s voltage and power limits are not exceeded. When you
want to increase more solar panels, and if the total power of the solar panels exceeds the allocation grid inverter, it is necessary to increase
the cost of a grid inverter.

3. Combination of SGPV does not interact -
The traditional solar grid tie system, they offer units ranging in high
power output and these
units are modular so you can have multiple units operating in parallel for large solar arrays. Although, the traditional grid inverter has MPPT
feature (Maximum Power Point Tracking), but the maximum power point is according to the entire series in terms of solar panels array, if the
performance of a piece of solar panels in the system, for some reason, such as leaves, bird droppings, dust, shadow, etc., degrades, the performance
of the entire solar power system will decrease.SGPV has no such disadvantage. If the performance of a piece of solar panels in the system degrades,
this just effects this piece itself, will not affect other SGPV in the system.

4. Improving the efficiency of the entire solar power system –
In traditional grid tie system, the solar panels are connected in
series, so the MPPT
of the inverter is according to the total panels in series, not to every panel, but there is difference between every panel, so not every panel is working
at the maximum power, this will reduce the total power of these panel in series.But SGPV has no such disadvantage. Because every inverter of SGPV
has MPPT function, so every panel is working at the maximum power, this will increase the efficiency of the entire system.

5. Low power consumption –
Most of the parts in the small grid-tie inverter are digital ICs and
low power MCU, so the power consumption of it is low,
though the quantity of grid tie inverters is increased, but this will not increase the power consumption of the entire system.

INSTALLATION :
The
individual system of SGPV is shown in Figure 1. Installing the solar
panel of the SGPV at a suitable location that sunshine can irradiate on
it,
connecting the cables of the solar panel to the DC input terminals of the small grid tie inverter of the SGPV, inserting the plug of the inverter into
the socket of the home grid. After this, when the sun shines, the SGPV will convert the solar energy to the home grid.

SGPV
can be stackable, and all SGPVs are independent each other. The total
power converting to the grid is the total power of all SGPVs. The
installation
of each SGPV is same. Connecting large quantity of SGPV to the grid, this will construct high-power grid-tie system.
