Description

Technical Field

[0001] This utility model relates to the field of photovoltaic energy storage equipment technology, specifically a photovoltaic energy storage inverter that is easy to wall-mount. Background Technology

[0002] Photovoltaic energy storage inverters are key devices in the renewable energy sector, operating on the basis of energy conversion and storage technology. First, when photovoltaic panels generate direct current (DC) under sunlight, this energy is transmitted to the energy storage inverter. The main function of the energy storage inverter is to convert the DC power generated by the photovoltaic panels into alternating current (AC) power for use in homes, industries, and businesses. During the power conversion process, the energy storage inverter also has energy storage capabilities. When the energy generated by the photovoltaic panels exceeds immediate demand, the excess energy is stored in the battery bank. Thus, when sunlight is insufficient or electricity demand is high, the energy in the battery bank can be converted back into AC power by the inverter to meet the demand.

[0003] Energy storage inverters contain battery packs and other equipment. The existing fixing method is usually to directly fix them to the wall with threaded fasteners. However, the battery packs inside the inverter need to be maintained every six months to a year. Maintenance and repair require disassembling the fasteners, which is cumbersome and inevitably damages the mounting holes each time it is disassembled, making it easy for the fasteners to loosen after reinstallation. Therefore, there is a need for a photovoltaic energy storage inverter that is easy to wall-mount to meet people's needs. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: Please refer to Figure 1-4 This utility model provides a technical solution: a photovoltaic energy storage inverter that is easy to wall-mount, including an inverter body 1 and a wall 4; in order to make it easy to disassemble and install the inverter when it is fixed on the wall so that its internal battery components can be maintained and repaired in the future, a base plate 5 is installed on the wall 4, a fixing ear 6 is fixedly installed on both sides of the base plate 5, a fixing device 2 is provided on the base plate 5, and a protective device 3 is provided on the top of the base plate 5.

[0023] The inverter body 1 can be movably mounted on the base plate 5 by the fixing device 2, making it convenient to install and remove the inverter body 1. The inverter body 1 is covered by the protective device 3 to prevent dust and rainwater from entering the interior of the inverter body 1.

[0024] To achieve the function of fixing the inverter body 1 and facilitating its installation and removal, the fixing device 2 includes a pair of L-shaped fixing plates 202. The inverter body 1 is mounted on the L-shaped fixing plates 202. A slider 201 is fixedly installed on one side of the L-shaped fixing plate 202. A sliding groove 200 is opened on the base plate 5. The L-shaped fixing plate 202 is slidably installed in the base plate 5 through the slider 201. A support plate 210 is fixedly installed on one side of the base plate 5. The support plate 210 is installed below the L-shaped fixing plate 202. A movable groove 203 is opened on the L-shaped fixing plate 202. A fixed part is fixed in the movable groove 203. A spring 204 is installed. A movable block 207 is slidably installed in the movable groove 203. A clamping plate 208 is fixedly installed on the movable block 207. A rubber pad 209 is fixedly installed on the clamping plate 208. One end of the spring 204 is fixedly connected to the inner wall of the movable groove 203, and the other end of the spring 204 is fixedly connected to the movable block 207. A limit groove 205 is opened in the movable groove 203. Limit blocks 206 are fixedly installed on both sides of the movable block 207 near the end of the spring 204. The limit blocks 206 are slidably installed in the limit groove 205. Wall 4 and fixing ears 6 are equipped with... The same expansion bolt 7 has a threaded fixing nut 8. In use, first fix the expansion bolt 7 to the wall 4, place the base plate 5 on the wall 4, ensuring the expansion bolt 7 passes through the fixing lug 6, and screw the fixing nut 8 onto the expansion bolt 7 to fix the base plate 5 to the wall 4. Insert the L-shaped fixing plate 202 into the sliding groove 200 via the slider 201. Then, place the inverter body 1 on the two L-shaped fixing plates 202. The L-shaped fixing plates 202 act as supports, suspending the inverter body 1 on the wall. The support plate 210 below the fixed plate 202 can serve as a support, which can distribute the force on the support plate 210. During installation, the clamping plate 208 is pulled to clamp the inverter body 1. The rubber pad 209 on the clamping plate 208 can prevent pinching. The elasticity of the spring 204 pulls the clamping plate 208 to clamp the inverter body 1, making it fixed on the L-shaped fixed plate 202 to prevent it from falling. During maintenance, the L-shaped fixed plate 202 and the inverter body 1 can be removed from the base plate 5 without repeatedly disassembling the fasteners, making the installation, disassembly and maintenance more convenient.

[0025] Example 2: As Figure 1 and Figure 4In order to protect the inverter body 1, the protective device 3 includes a cover 301. The cover 301 is installed on the base plate 5. A plug 302 is fixedly installed at the bottom of the cover 301. The base plate 5 has a plug hole 300. The plug 302 is slidably installed in the plug hole 300. After installation, by inserting the plug 302 into the plug hole 300, the cover 301 can wrap the inverter body 1. The cover 301 can prevent rainwater and dust from entering from the ventilation holes on the inverter body 1. It can prevent rainwater and dust from entering the inverter body 1 through the ventilation holes when the inverter body 1 is installed outdoors, which would cause damage to the equipment. The bottom of the cover 301 is open, which can not affect the normal airflow and external circulation and will not affect heat dissipation. The remaining features are the same as in embodiment 1.

[0026] The working principle is as follows: First, fix the expansion bolts 7 to the wall 4. Place the base plate 5 on the wall 4, ensuring the expansion bolts 7 pass through the fixing ears 6. Screw the fixing nut 8 onto the expansion bolts 7 to fix the base plate 5 to the wall 4. Insert the L-shaped fixing plate 202 into the sliding groove 200 via the slider 201. Then, place the inverter body 1 on the two L-shaped fixing plates 202. The L-shaped fixing plates 202 act as supports, suspending the inverter body 1 on the wall. The support plate 210 below the L-shaped fixing plates 202 also serves as a support, distributing the force on the support plate 210. During installation, pull the clamping plate 208 to clamp the inverter body 1. The rubber pad 209 on the clamping plate 208 prevents pinching damage. The spring 204 pulls the clamping plate 208 to hold the inverter body 1, fixing it on the L-shaped fixing plate 202 to prevent it from falling. During maintenance, the L-shaped fixing plate 202 and the inverter body 1 can be removed from the base plate 5 without repeatedly disassembling the fasteners, making installation and maintenance more convenient. After installation, by inserting the plug 302 into the plug hole 300, the cover 301 can wrap the inverter body 1. The cover 301 can prevent rainwater and dust from entering through the ventilation holes on the inverter body 1, thus preventing rainwater and dust from entering the inverter body 1 through the ventilation holes when the inverter body 1 is installed outdoors and causing damage to the equipment. The bottom of the cover 301 is open, which can not affect the normal airflow and external circulation and will not affect heat dissipation.
