Product Description

Product Introduction.

This Grid Tie Power Inverter is the world’s most technologically advanced inverter for use in utility-interactive applications. This integrated system maximizes energy harvest, increases system reliability, and implifies design, installation and management. The small type solar grid tie power inverter can obtain the solar energy from solar panel, and can tie to the grid through its output cables with no extra equipment. The installation is very convenient and reliable.

We call the system combining with small solar grid tie inverter and solar panels as ‘SGPV’. The system includes solar panels and small type grid tie inverter and installation kit. Solar panels can be mono silicon, polygon silicon, non-crystal film or any other material that can transform solar energy to electric energy. The power of grid tie inverter should be matched to the power of solar panels connected. So the power of SGPV is defined by its solar panels, it can be standardization according to the actual using.

The inverter can be connected to any outlets of utility grid at house. The small grid tie inverter monitors the volume, frequency and phase of the home utility grid, then produce pure sine wave AC power that the frequency and phase are as same as the grid's, and the volume is a bit higher than the grid's, then according to the current controlled PWM, to control the output power to the grid. The small grid tie inverter just puts out power when the home grid is on. When the sun shines, the PV panel will produces DC voltage, and the grid tie inverter will change the DC voltage to AC voltage and puts out power to the home grid. When the total power of electric apparatus that are using in the house is larger than the output power of the inverters, these power from the inverters will be consumed in the house, this will slow down the power meter, otherwise, the difference of the output power of the inverter between the total used power of the apparatus will go out from the house to the out grid.

A Small Grid Tie Power System with the MSC Grid Tie Inverter

Multiple inverters can be connected in parallel to creat bigger system.

Advantage of The MSC Grid Tie Power System

There are many advantages of SGPV compare with the traditional grid tie power 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 just needs 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 erformance of a piece of solar panels in the system, for some reason, such as leaves, bird droppings, dust, shadow, etc. and 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 much of the entire system.

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.

Installation Instructions

Installing MSC Grid Tie Power System involves several key steps:

9. Completing Sunshine installation map and Connecting the PV modules.

Example of Installation of 1KW grid tie power system.

In order to explain the installing operation, we assume that there is a house that the usual electricity consumption is about 5KWH per day, and the real irradiation time is about 5 hours.1, Considering the total capacity of the grid tie power system that you need. As we stated at Step1, we can get a result that a 1kW Sunshine Grid Tie Power System is suitable for this house, so we will establish a 1KW gird tie power system step by step, we also assume that we will install the system in the house where the utility grid is 230V/50Hz.

2, Choosing applicables Solar Panels. Because the most popular solar panels are 240Wp~250Wp poly panels with 60 PCS solar cells,

3, Selecting Accessory for Grid Tie Power System installation. Because we should connect 4 PCS solar panels to Sunshine Grid Tie Inverter, so some connectors are necessary. Consider of the Voc, Vmp and Isc, we choose some MC4 connectors and some connectors for parallel connecting.

4, Selecting correct model of MSC Grid Power Inverter. Because maybe there will be several methods of

Limit Function Connecting Instruction

Connecting method for single phase AC grid: The limit sensor should be clamped on the live line at the position before the loads access points, and the inverter access point can be at any position on the same live line, see picture 1. The inverter with limit function will just produce power that is less than total power consuming by loads that connected after the position that the limit sensor clamped. The inverter will not measure loads’ power that connected before the point of the limit sensor clamped..

Connecting method for three phases AC grid: If your AC grid is three phases grid, and also you have more grid tie inverters, then you can connect inverters to three phases individually. Please see picture 2. These 3 inverters will not affect each other. G line will be connected as normal.
