Product Description

HQRP 500W Grid Tie MPPT Power Inverter. The grid-tie inverter transfers solar energy directly from the solar panel into the home grid, no extra equipment is needed. It controls the phase, the frequency and voltage of the power generated by the solar panel. It can be connected to any outlet (conventional network) in the home. The grid-tie inverter produces a pure sine-wave and matches that of the grid. HQRP UV Chain / UV Radiation Tester: To know the Solar UV Index, it is enough to compare the colorchange with the 4 standard colors around. Very light purple: low intensity, UV index 1-2. Sun-protection not necessary. Light purple: medium intensity, UV index 3-5. Sun-protection is recommended. Purple: strong intensity, UV index 6-7. Sun-protection is necessary. Dark purple: very strong intensity, UV index 8-11. This tester shows you the level of UV radiation and helps you protect your eyes and skin from negative sunlight effect.

HQRP 500W Grid Tie MPPT Power Inverter 10.5V~28V DC 110V~120V AC for Solar Panel System plus HQRP UV Chain / UV Radiation He Review

I hooked this up to two 100 watt solar panels wired in parallel and I haven't been able to draw more than 155 watts (of the 200 watt rating) measured at the panels when measured with a Watts Up meter. Voltage is draw down to around 14 volts when the optimum range for the panels should be closer to 18 volts, so I'm certain there's a loss factor with this device.

Measured draw shows it slowly ramps up wattage over about 30 seconds when first brought online and shuts down properly when grid power is removed. This doesn't appear to have a UL rating, so that can be an issue with your power company / using the device in the US.
