Input Voltage(V): 60 Output Current(A): 2.2 Output Frequency: 60

Product Description:


To ensure the BDM-300X2 is not disconnected from the PV modules under load, adhere to the following disconnection steps in the order shown:

1. Disconnect the AC by opening the branch circuit breaker.

2. Disconnect the first AC connector in the branch circuit.

3. Cover the module with an opaque cover.

4. Using a DC current probe, verify there is no current flowing in the DC wires between the PV module and the BDM-300X2.

5. Care should be taken when measuring DC currents, most clamp-on meters must be zeroed first and tend to drift with time.

6. Disconnect the PV module DC wire connectors from the BDM-300X2.

7. Remove the BDM-300X2 from the PV array racking.

Installing a replacement BDM-300X2

1. Attach the replacement BDM-300X2 to the PV module racking using hardware recommended by your module racking vendor


2. Connect the AC cable of the replacement BDM-300X2 and the neighboring BDM-300X2 to complete the branch circuit connections.

3. Complete the connection map and connect the PV Modules.

1) Complete the connection map

2) Each BDM-300X2 has a removable serial number located on the mounting plate. Enter this serial number into a BDG-256, and correspond it to a number in the connection map.

3) Connect the PV Modules

4) Completely install all BDM-300X2 and all system inter-wiring connections prior to installing the PV modules.

a) Mount the PV modules above their corresponding BDM-300X2. Each BDM-300X2 comes with two oppositely sexed DC connectors.

b) First connect the positive DC wire from the PV module to the negatively marked DC connector (male pin) of the BDM-300X2. Then connect the negative DC wire from the PV module to the positively marked DC connector (female socket) of the BDM-300X2. Repeat for all remaining PV modules using one BDM-300X2 for each module.

Q:In a photovoltaic grid-connected project, the role of the inverter is to convert the voltage into AC 220V or 380V for the grid, since the transformer will raise the voltage again
Spontaneous use is a way of grid, that is issued to the electricity, mainly their own family or internal use, the excess part of the power to the grid
Q:Installation and maintenance of photovoltaic grid - connected inverter
photovoltaic systems Power generation system used in the cable must be connected firmly, good insulation and specifications appropriate.
Q:The working principle of photovoltaic grid - connected inverter
Full-bridge inverter circuit to overcome the shortcomings of the push-pull circuit, the power transistor to adjust the output pulse width, the output AC voltage RMS that changes. Since the circuit has a freewheeling circuit, even if the inductive load, the output voltage waveform will not be distorted. The disadvantage of this circuit is that the upper and lower arms of the power transistor are not common, so you must use a special drive circuit or use isolated power supply. In addition, in order to prevent the upper and lower arm co-conduction, must be designed to turn off after the conduction circuit, that must be set dead time, the circuit structure is more complex.
Q:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
Widely used in air conditioning, home theater, electric wheel, power tools, sewing machines, DVD, VCD, computer, TV, washing machine, range hood, refrigerator, video recorders, massage, fan, lighting and so on.
Q:How the output voltage of the PV inverter and the grid-connected voltage are determined
due to the higher penetration rate of the car to go out to work or travel can be connected with the inverter battery drive electrical and various tools work. The car inverter output through the cigarette lighter is 20W, 40W, 80W, 120W to 150W power specifications. And then a large number of power inverter power
Q:What are the methods of photovoltaic grid-connected inverter control
and can set the dead time between the upper and lower arms, the use of INTEL 80C196MC to achieve sine wave output circuit, 80C196MC to complete the sine wave signal, AC output voltage, to achieve regulation. Circuit output generally use LC circuit filter high frequency wave, get pure sine wave.
Q:What is the difference between a PV grid-connected inverter and an off-grid inverter?
Grid-connected inverter does not need energy storage, but the energy can not be controlled, the number of photovoltaic sent to send online how much, simply do not want people to.
Q:After the PV inverter, how to achieve the same period before the network?
Solar panel simulator: with MPPT function, simulated morning, noon, afternoon, evening, rainy weather, solar panels produced under different conditions in different voltages.
Q:Photovoltaic grid-connected inverter without DC emc how will happen
can convert light energy into electricity, so that the current flow from one side to the other, the general can be issued equivalent to 10 to 20% of the received light energy. In general, the stronger the light, the more electricity is generated. Its working principle is based on the semiconductor PN junction of the photovoltaic effect. The so-called photodynamic effect is when the object by the light, the object within the charge distribution of the state of the electromotive force and current generated an effect.
Q:Generally a large grid-connected photovoltaic power plant will have several inverters
Inverter, a single failure, does not affect other operations, the impact on the grid is small, high reliability.
