Output Power: 500 Inveter Efficiency: 95.5% Output Voltage(V): 240
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:Grid-connected inverter is generally divided into photovoltaic power generation grid-connected inverter, wind power grid-connected inverter, power equipment and grid-connected inverter and other power generation equipment power generation inverter.
Grid-connected inverter is generally used with large-scale photovoltaic power plant system, a lot of parallel PV string is connected to the same set of inverter DC input, the general power of the use of three-phase IGBT power module, power
Q:What is the difference between low voltage grid connection and medium voltage grid connection?
The difference is that the current at low voltage and the grid is large, the current is small when the voltage is small, followed by the low voltage crossing parameter setting problem (such as PV inverter integrated with inverter and low voltage crossing function, not all photovoltaic inverter
Q:Is the PV inverter a current source or a voltage source?
Photovoltaic inverter, also known as power regulator, according to the inverter in the use of photovoltaic power generation system can be divided into two kinds of independent power supply and grid.
Q:What is the difference between a PV grid-connected inverter and an off-grid inverter?
Offline generally need energy storage, not to send energy online. Power grid has no right to interfere.
Q:Installation and maintenance of photovoltaic grid - connected inverter
, any failure that affects the safety performance of the inverter must be immediately removed before turning on the inverter again.
Q:Solar grid inverter does not merge into the grid, direct access to the load to the load power supply?
Inverter is the DC power (battery, battery) into alternating current (usually 220V, 50Hz sine wave). It consists of inverter bridge, control logic and filter circuit
Q:Photovoltaic grid-connected inverter without DC emc how will happen
Solar photovoltaic power generation technology is the use of solar cells, the photovoltaic effect of semiconductor materials, solar radiation can be directly converted into a new type of power generation system, solar energy is a radiant energy, solar power means --- to direct conversion of sunlight Into electricity,
Q:After the PV inverter, how to achieve the same period before the network?
Grid simulator: analog power grid, normal and abnormal conditions, overvoltage, undervoltage, over frequency, under frequency, sudden power failure, etc.
Q:Photovoltaic grid-connected inverter problem
Hello, the definition of the zero line is not caused by the transformer three-phase electric tail connection? I now do not understand why there is no isolation transformer AC output marked is N (zero line), and it is not the transformer three-phase power of the tail connection leads to, this is the zero line? The The
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.
