Photovoltaic panels also have efficiency degradation during actual use, such as shelter from leaves and dust on the surface of the photovoltaic panel, temperature, and mounting angle of the bracket. Regular cleaning of impurities on the surface of photovoltaic panels can increase the power generation rate.

How to solve the automatic trip of the AC circuit breaker:

The output circuit breaker tripping generally indicates that there is a short circuit in the circuit. Such a situation occurs frequently. It may be that the internal drive board of the inverter has a short circuit, and the drive board and IGBT need to be replaced.

Yes, non-standard software needs to be customized. Note that the three-phase 220VAC current is nearly twice as large as the 380VAC current, so it needs to be used at reduced power.

The mainstream of the anti-reverse solution is to use external CT and smart meters to realize the grid anti-reverse function. The smart meters adjust the output power of the inverter through 485 communication, and realize the self-generation of photovoltaic electricity. The plan requires the purchase of a special anti-reverse model, CT and smart meter, and the anti-reverse function need turned on in the settings.

1. Three phase photovoltaic energy storage system is usually the best choice for three-phase household application scenarios of court power, or industrial and commercial application scenarios such as shopping centers, parking lots and stations, with unbalanced output function. In order to realize unbalanced output, intelligent ammeter with CT function is usually used to monitor the load consumption of each phase in real-time operation, so that the inverter can adjust the output power of each phase accordingly
2. Seamless switching of power failure: UPS level off grid switching means that the switching time of standby power supply from grid connected mode to off grid mode is less than 20ms, which is the time that most ordinary household loads can pass through without cutting off the power supply.

BD series support solar charge and solar on-grid function.BD-RBP only suppprt grid energy stroage and discharge function.Used for system retrofit.

BD support on-grid output,sales electricity to government.XN series don't support this.

Don 't support in off-grid mode,off gird mode need distribute to load power.Only support in on-grid mode.

When using double-sided modules, pay attention to the following when choosing an inverter:
One is not to overmatch, because bifacial modules can sometimes increase power generation by 20% to 30%, that is to say, increase output power. It is recommended that modules and inverters be configured at 0.9:1.
Second, when the power of the module increases, only the current can increase, but the voltage will not increase. Therefore, it is necessary to choose an inverter whose input string current is greater than 12A.
