Smaller size Hoymiles model HMS-2000D-4T) Shopee ???? https://s.shopee.co.th/50EMtR3sav LAZADA ???? https://s.lazada.co.th/s.oHRFZ?cc Hello, welcome everyone to the ZimZimDIY channel. For today, I will take my friends to unbox and get to know a Microinverter. Which is used in the Ongrid system is considered the top model in the 1-phase model at the moment from the Hoymiles camp. Normally, in the Ongird system, it will produce DC power from the solar panels through the Inverter and then output AC power, right? It must be connected to the grid of the house electricity. Or connected in parallel to the house electricity Like this But not connected like this. Let's give an easy example. For this system, many people like to use it because it pays off quickly. It is suitable for people who like to use a lot of electricity during the day or work at home because this system does not use batteries. We use only the amount of electricity we produce. If the panel does not produce enough electricity, we will get electricity from the electricity authority to help. Or if the electricity is produced in excess, we can sell it to the electricity authority, but we must sign a contract to buy electricity from the electricity authority first. However, the Ongrid system will only work when the transmission line from the electricity authority is supplied. If the transmission line is out, the Micro Inverter will also be out of power. For safety reasons, the On grid system is mainly divided into 2 types: String Inverter and Microinverter. The String Inverter type is simply the traditional type that we commonly see, which is to connect multiple solar panels. Connected together and will be connected in series + collide - continuously. Will connect 8 panels or 10 panels or 20 panels, it's up to you. It will get DC high Vote power. The voltage will be around 2-300V up to almost 1,000V. Many people call this loop connection a String and a String connection must use a String Inverter inverter. Advantages 1. Use only one inverter 2. Easy service, can be installed in the house 3. Affordable price But in the On grid system, there is still another energy conversion system. That is popular and many people say it is safe, which is the Micro inverter. The Micro inverter itself converts power from DC to AC as well. But this inverter will be installed under the panel. On the roof And produces 220V AC power produced from the roof. The advantages are 1. Can monitor each panel to see how much power each panel produces, how many watts. 2. If one of the panels is off It does not affect the remaining panels. 3. Save space below Because the equipment is installed on the roof. Just pull the wire down. Its shape. Of course, if installed on the roof, the shape must be a bit flat. There are fins around the body to dissipate heat as much as possible. Looking at it, it looks like a sea crab. They have high quality MC-4 heads installed from the factory. As I said, it can be installed 4 panels at the same time. That is, 2 left panels, 2 right panels. And connect to each panel, the voltage is low. It is considered to be in the Rapid Shutdown Inside Array Boundary standard. The top is the Output connector that we will connect to use. Inside, there will be 3 conductor wires, which are LNG. This part is the signal receiving and transmitting pole. There is a carrying handle and a slot to attach to the installation point. The bottom will be 1 status light. Let's take a look at the back of the machine. The nameplate states that it can support a general voltage of 16-60V DC. Minimum voltage It starts working at 22V DC, supports a maximum voltage of not more than 65V DC, supports a maximum continuous current of 16A per channel, supports a short-term current of not more than 25A per channel, the maximum output power is 2,000VA, and because its Power Factor is very low, which is almost 1, if calculated in watts, it is almost 2,000W. The maximum output current is 8.7A, and the output voltage will automatically imitate the voltage / and frequency of the home grid. When we connect, the energy conversion efficiency is as high as 96.5%, dustproof and waterproof at IP67 level, operating temperature is from -40 degrees to 65C. It has been tested by immersing it in water at a depth of 1 meter for 1 minute. It turned out that it could withstand it. Therefore, if we install it on the roof, it can handle dust, steam, water vapor, rain spray or water drops very easily. For this model, it is listed by the Metropolitan Electricity Authority and the regions. You can request permission and install it. If it's a complete set like this, it's called a 1-phase 2kW set. If you're interested, want to buy it to install yourself, or are an experienced technician, you can go see the products from the distributors under th
