Suitable for all transformer
Board Size: 23.5cm x 11.2cm x 8cm Dimensions: 22.5cm x 10.3cm Board Weight: about 1000g The power supply line is connected in series with a 125A air switch, the interface with the motherboard to solder welding firm, power transmission to instant, not intermittent, high power to increase heat dissipation. Power frequency pure sine wave inverter board, highly efficient and stable circuit, no-load current is small (<0.5A), battery voltage / overload / overheat protection, installed simple suitable for any transformer Before You Buy Note: 12V input, maximum power of 1500 AV (Real power) Peak:3000AV-4500AV 24V input, maximum power of 3000 AV (Real power) Peak:6000AV-9000AV 36V input, maximum power of 4000 AV (Real power) Peak:8000AV-12000AV 48V input, maximum power of 5500 AV (Real power) Peak:11000AV-16500AV 60V input, maximum power of 6500 AV (Real power) Peak:13000AV-19500AV Transformer requirements: 1000W transformer about 5 kg, 2000W transformer about 10 kg, 3000W transformer about 15 kg. Support transformer series or parallel. Tips: The product needs to connect the corresponding transformer to work. The product price does not include transformer 12V battery, Use about 7V transformer (220V to 6-8V) 24V battery, Use about 14V transformer (220V to 12-16V) 36V battery, Use about 20V transformer (220V to 18-22V) 48V battery, Use about 28V transformer (220V to 24-32V) 60V battery, Use about 32V transformer (220V to 31-39V) The product supports the transformer power is not limited, 50W or 2000W, or 5000W or 10000W or transformers in parallel or transformers in series. Transformer output corresponding voltage can work properly. The output power is determined by the input voltage and the transformer used has many relationships. For example: you use the 24V battery pack input, while using the 5000W transformer, the maximum output is only 2000W. Because you are using a 24V voltage input. However, if you use the transformer maximum power is only 300W, the maximum output power is only 300W, and the transformer heat is serious. Please do not worry. For example: when you buy the product is selected 24V input, the maximum power is only 3000W. However, later want to use 48V input how to do? I am in the design of the circuit, has been considered for everyone. You only need to replace the corresponding transformer and replace the motherboard R1 and R2 resistor can achieve 48V input, can achieve 5500W output. 60V input, but also need to replace the output capacitor, I suggest you buy 60V input products directly. 12V Input: R1 = 10K; R2 = 0K 24V Input: R1 = 39K; R2 = 20K 36V Input: R1 = 68K; R2 = 47K 48V Input: R1 = 91K; R2 = 62K 60V Input: R1 = 110K; R2 = 91K
Battery connected to the motherboard needs series 125A air switch, the motherboard needs Instant Energized.

Inductor:
(
The inductor is used to reduce the no-load current,
You can choose to use or not use
)
But, more magnetic leakage of the transformer, it is recommended to use.

If the machine is installed, the no-load current is large, it is necessary in the transformer low-side series inductance (inductance toroidal transformer must series connection).

Frequency sine wave inverter board Function:
1. Low Battery Protection:
When the battery voltage is lower than 10.5V each section, the inverter will turn off the inverter (this time without AC voltage output), the inverter is in standby mode.
2. Battery voltage protection:
When the battery voltage is higher than 15V each section, the inverter will turn off the inverter into standby mode.
3. The battery is OK to start automatically:
When the battery voltage protection, when the solar wind or charge the battery charged to 13V each section, the inverter automatically start output AC voltage supply to the load. When the battery voltage protection 15V overvoltage protection and then return to each section, the inverter automatically start.
4. The temperature-controlled fan, and overtemperature protection:
The inverter does not turn the fan is working properly, when the temperature is too high, fan automatic operation, when the temperature drops, the fan automatically stops running. When the fan is damaged, the temperature is too high, the inverter will turn off the inverter into standby mode.
When the temperature drops, and automatically starts the inverter output AC.
5. Impact and short circuit protection:
The inverter apparatus sometimes real hardware Zhu Bo-limiting flow protection, and software delay (400mS) short-circuit protection plus frequency isolation transformer. Improve product reliability impact resistance of the product.
Recently, many buyers to buy my products are worried that can‘t find a suitable transformer, in fact, the transformer is easy to match, the following circuit diagram can use low-power transformers to high-power transformers.
Solve everyone DIY transformer
Buyers use examples:
Transformers in parallel
Transformer in series
You can achieve the desired power transformers in parallel or in series.

The above price is the price of the motherboard (including pure sine inverter board + 5UF capacitor), excluding local country customs duties.
Products are constantly updated, and the appearance of the product you receive may be slightly different, but the performance is the same. No further notice.
Hello everyone!
Too many recent customers to buy the motherboard, fear can not buy a suitable transformer, following a simple method of making suitable transformer.
Hello everyone! A lot of people in the use of the inverter, it is still not able to test the inverter is not a sine inverter. In fact, very simple to identify. The inverter output power to provide electricity for the audio system, pure sine wave inverter waveform clean, sound does not appear the current sound or noise, if the speaker sends the current sound or noise, it can determine the pure sine wave inverter the inverter is not clean or square wave inverter. You can test my products, and then give me feedback.
Product updates, component layout may be slightly different, no longer notice.

Warm hint: at present, some network stores are selling the inverter main board of the type of our shop. The main board of this type of inverter uses low price electronic components, and the general consumer can't identify it. However, with the use of time, the problem is becoming more and more prominent. For example, the main board heating of inverter is serious, MOS tube burst, capacitor burst, power conversion efficiency is too low and so on. The following picture, I explain the problem.
