Problems solved by technology

[0003] 1. Customers cannot choose whether the solar panel will charge the battery first or the national electricity will charge the battery
[0004] 2. The standby loss is too large (the inverter consumes too much power when it is turned on)
[0005] 3. The charging current cannot be adjusted when charging the battery with the national electricity
[0006] 4. Unable to display the reason why the solar inverter shuts down
[0007] 5. The solar panel power generation parameters cannot be displayed and recorded in the inverter
[0008] 6. Unable to switch on and off at regular intervals
[0009] 7. The voltage of a single battery cannot be seen
[0012] 10. It is impossible to view all aspects of solar inverter data remotely

Embodiment Construction

[0025] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Such as figure 1 As shown, the solar inverter of the present invention includes a photovoltaic input terminal, a commercial power input terminal, a switch module, a storage battery connection terminal, an inverter module and a DSP controller module. Both the photovoltaic input terminal and the mains input terminal are connected to the battery connection terminal through the switcher module; so that the system can perform output switching control according to the user's settings or the conditions of the battery and the mains power, so as to achieve stable output and maximize power generation. The specific switching Conditions belong to the category of man-made regulations, and are not considered in the present invention; specifically, it also includes an AC voltage stabilization control module, and the mains input terminal is co...

Abstract

The present invention provides a solar inverter which comprises a photovoltaic input end, a mains supply input end, a switch module, a storage battery connection end, an inverter module and a DSP controller module. The photovoltaic input end and the mains supply input end are connected to the storage battery connection end through the switch module. The storage battery connection end is connected to the inverter module. The DSP controller module is connected to the switch module. The inverter is provided with an AC output end. According to the solar inverter, the switch of photovoltaic input and AC input can be realized, a system parameter is recorded, and the actual use need is satisfied.

Description

technical field [0001] The invention relates to the field of photovoltaic power generation, in particular to a solar inverter system. Background technique [0002] At present, solar inverters (below 10KW) on the market only have a simple inverter function, which is to convert direct current into alternating current, which has the following disadvantages: [0003] 1. Customers cannot choose whether to charge the battery with the solar panel first or the national electricity to charge the battery. [0004] 2. The standby loss is too large (the inverter consumes too much power when it is on). [0005] 3. The charging current cannot be adjusted when charging the battery with the national electricity. [0006] 4. It cannot display the reason why the solar inverter is shut down. [0007] 5. The power generation parameters of solar panels cannot be displayed and recorded in the inverter. [0008] 6. Unable to switch on and off at regular intervals. [0009] 7. The voltage of a...
