Deye Sun 50K-SG01HP3-EU-BM4 Three-phase hybrid inverter 50KW

Do I need external overcurrent protection for systems rated at 50 kW or above?

No. The inverter has an integrated anti-islanding circuit and complies with all relevant standards such as VDE-AR-N 4105, EN 50549 and G99. Additional NA protection is therefore not required.

Which high-voltage storage units are approved?

Officially compatible models include, among others, the BYD HVS/HVM, Pylontech Force H1/H2, Dyness Tower and the Deye GB-L series. Communication takes place via CAN or RS485, depending on the model. The correct setup number is entered directly in the ‘Battery → Lithium → Setup Number’ menu or set via DIP switches. According to the supplier, other storage solutions such as BOS-G are already pre-configured. It is recommended that you check the model against the compatibility list, as changes to the protocols can occur from time to time.

How many kWp can I connect without clipping?

According to the data sheet, the maximum DC input power is 65,000 W. In practice, a generator size of 60 to 65 kWp is considered optimal. Only above this limit may minor clipping losses occur on a few days of high load, which remain below two per cent over the course of a year. However, it is recommended to remain below 65 kW. The starting voltage of the solar modules is the decisive factor here.

Can I connect several 50-kW units in parallel?

Yes. Up to ten inverters may be operated in parallel, both grid-connected and off-grid. One unit acts as the master, including the CT sensor connection, whilst the remaining units automatically follow as part of the array.

Do I need special ventilation?

Active air conditioning is not required. The inverter operates with intelligent air cooling and is designed for ambient temperatures of up to 60 °C. The maximum noise level is 65 dB(A) under full load; in standby mode, the unit remains virtually silent. Good air circulation is essential, for example in a ventilated plant room or at a sheltered outdoor location. The fan inlets and outlets must remain unobstructed; otherwise, charging problems may occur.
