Conversion of direct current (DC) power from solar cells to alternating current (AC) power required in residential AC lines usually employs a large number of batteries for storing DC electrical energy from solar cells during day-time. The batteries serve as a DC voltage source. The DC voltage source is then converted to simulate sinusoidal ac voltage by a number of methods. One such method uses an asynchronous sine-wave generator or a digital technique to mimic an AC voltage having a plurality of DC levels. To couple such converted AC voltage to the residential AC line, the phase, frequency and amplitude of the converted AC voltage must be the same as that in the residential AC line. If these parameters are not synchronized, serious problems to the municipal electrical supply, and/or to the converted solar source would result.

A novel solar inverter circuit (US5898585A) is used to connect a solar photovoltaic (PV) array with an alternating current (AC) voltage source to convert direct current (DC) power from the PV array to AC power. The solar inverter circuit employs the current-voltage (I-V) characteristic of the PV or solar cell, and an H-Bridge circuit with gate controller. The gate controller synchronizes the H-bridge with the AC voltage source. The PV array and the solar inverter circuit can plug directly into a residential AC plug and provides electrical power as a supplementary AC supply. Electrical energy required by the home appliances is supplied by the municipal AC line and solar energy concurrently. Advantages of the solar inverter circuit of the present invention include the flexibility of using the solar inverter circuit with any number of solar cell panels through the implementation of an impedance transformer, and the implementation of an additional, optional output for DC battery charging.

In order to overcome the shortcoming of low stability of a thermal insulation layer of an conventional polystyrene board anchored by a mechanical fixing device, the present invention provides a reinforced polystyrene board which is able to improve a tensile strength and a folding strength thereof, so as to enhance mechanical properties and whole stability of an external thermal insulation system of the polystyrene board.

A technical scheme adopted by the present invention is as follows. A two-dimensional grid rein forcer is disposed in a surface layer of a thermal insulation polystyrene board. The grid rein forcer is made of a glass fiber grid, a metal grid or a man-made fibers grid. A characteristic of the grid reinforce is that a polystyrene board protective layer is disposed on an outer surface of the grid rein forcer, which isolates the grid reinforce from an external environment of the polystyrene board, such as a thin layer of plastering mortar on the polystyrene board surface, and improves corrosion resistance and durability of the thermal insulation polystyrene board. A glass fiber grid rein forcer can be disposed in double sides or single side of the polystyrene board, according to requirement.

The glass fiber grid rein forcer is formed by knitting decussations of glass fiber warps and wefts. A distance between the grid apertures of the glass fiber grid rein forcer is 5 25 * 5 25mm, optimally 7 15 * 7~15mm; a thickness of a polystyrene board protective layer of the rein forcer, i.e., a distance between the glass fiber grid rein forcer and an outer surface edge of the polystyrene board is 5~15mm, optimally 8~12mm.

The metal fiber grid rein forcer mentioned above is formed by electric welding decussations of longitudinal steel wires and transverse steel wires. A distance between the grid apertures of the metal fiber grid reinforce is 5~60*5 60mm, optimally 10~30* 10~30mm; the metal fiber grid rein forcer is hot-galvanized steel wire, cold drawn low carbon steel wire, stainless steel wire or alloy steel wire. A diameter of the steel wire is 0.5~4.0mm, optimally 0.9~2.5mm. A thickness of a metal fiber grid polystyrene board protective layer of the rein forcer is 5 50mm, optimally 8 30mm.

The man-made fibers grid mentioned above is formed by knitting decussating of man-made fibers warps and man-made fibers wefts. A distance between the grid apertures of the man-made fibers grid rein forcer is 5*5 20*20mm, optimally 10* 10~15*15mm; a thickness of a polystyrene board protective layer of the man-made fibers grid reinforcer is 5~15mm, optimally 8~12mm.

By using a method that accomplishes compression molding the grid rein forcer and the polystyrene board at a time, the present invention disposes the grid rein forcer in the surface layer of the polystyrene board, so as to ensure the integrity and air tightness of the polystyrene board body that is inside or outside the grid rein forcer.

The present invention reinforced polystyrene board has the advantages as follows. Compared with a conventional polystyrene board, the reinforced polystyrene board significantly improves tensile strength and folding strength thereof. The present invention is suitable for an external thermal insulation wall of the polystyrene board anchored by a mechanical fixing device, and can solve a problem that the polystyrene board has the shortcomings of brittleness and easy breaking.
