If floors are different in the leveling error, adjust each position of flashboard to keep the same errors on every floor, and adjust creeping speed of elevator (set by multi-step speed) and P09.16 (stop S-curve end segment duration).

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.

In the field of household energy storage, lithium battery has greatly exceeded the lead-acid battery with the advantages of small volume, long service life and high safety. Battery selection is a complex process. In addition to considering the load, many other factors need to be considered, such as battery charge and discharge capacity, maximum power of energy storage machine, power consumption period of load, actual maximum discharge of battery, specific application scenarios, etc. in order to select battery capacity more reasonably.

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.

The popular understanding of double-glass double-sided modules is that the front and back sides of the module can generate electricity. The front of the module receives direct sunlight to generate electricity, and the back of the module absorbs background reflected light and surrounding scattered light to generate electricity. When conditions are ideal, It can increase the power generation of modules by 20% to 30%. Generally, the lighter the color of the object, the higher the reflectivity of the object. The more the power generation of the components increases.

The anti-reverse current of the DC terminal is mainly realized by anti-reverse diode;
The anti-reverse on the AC side is mainly realized by the current detection device (two-way smart meter and CT) at the grid connection point. An inverter is equipped with a two-way smart meter and a current transformer. The inverter and the meter communicate through the 485 interface. The two-way meter is installed at the grid connection point. When the inverter detects that the meter has current flowing to the grid, it immediately changes its working mode. , From the MPPT maximum power tracking mode to the control output power mode, the output power of the inverter is almost equal to the load power.
