Huawei FusionSolar Commercial & Residential PV Solution

*2. Only applicable for PV string. The maximum input voltage and operating voltage upper limit will be reduced to 495 V when inverter connects and works with LG battery. *3. VDE-AR-N

Detailed explanation of Huawei photovoltaic inverter parameters

This document provides information about the ModBus protocol used in Huawei inverters,and can be used to regulate and restrict follow-up third-party integration R&D and customizations.

Using Huawei SUN2000 inverters with high /A ratios

Provided that the system is designed with these constraints in mind, high DC/AC ratios will not cause any detrimental effects to the reliability, lifetime or warranty of Huawei SUN2000 inverters.

FAQs 6

Does Huawei have a DC/AC Ratio limit on solar inverters?

ads in low-light conditions during the winter season.Huawei has designed the SUN2000 solar inverters such that they can operate in “clipping” mode for sustained periods of time. Therefore, Huawei will not pose firm limits on the DC/AC ratios on its inverters, provided that the desi n

What is a large DC-to-AC ratio in a Huawei inverter?

r to such a setup as an “oversized installation”. In these cases, the so-called “DC-to-AC ratio” is larger than 1, or larger than 10 if you like to use percents rather than fractions. Huawei inverters are designed to automatically limit the maximum output power stated on their type plate, regardless o

What is the maximum power allowed in a PV module?

Max. Total Harmonic Distortion Max. Operating Altitude without Derating *1 The maximum power of PV module at STC shall NOT exceed the “Rated input DC power” of MERC -1100/1300W-P.PV Modules with up to +5% power tolerance are allowed. *2 Any power optimizer, which is connected to an operating inverter in a PV string, will be bypassed when it fails.

What is the maximum input voltage for a smart string inverter?

Smart String Inverter Recommended max. PV power *1 The maximum input voltage is the upper limit of the DC voltage. Any higher input DC voltage would probably damage inverter. *2 Any DC input voltage beyond the operating voltage range may result in inverter improper operating.

What are the requirements for a full power inverter?

Require standard 60 cells module to meet the inverter minimum startup voltage *7 Full power capability refers to online smart design tool. Max. Devices Supported

What if the inverter has no output power?

When the inverter has no output power, set this parameter to Positive if the active power reading of the power meter is positive. Otherwise, set this parameter to Reverse. Total power: controls the total power at the grid-tied point to limit the power fed to the power grid.
