Microinverter HM-400 1F Hoymiles

Description

The world’s first single Daisy-Chain microinverter with an extremely wide range of DC input operating voltage (16-60 V) and low start-up voltage (only 22 V). System with an odd number of panels with CEC No. 1 weighted efficiency in the world – 96.5% (peak efficiency – 96.7%) in 2015. The microinverter complies with VDE-AR-N 4105: 2018 and EN50549-1: 2019.

IMPORTANT: For each installation built with Hoymiles microinverters, a Hoymiles monitoring module must be selected. For this model, the choice is DTU-Pro or DTU-Lite.

Product distinguishing features:

• Safer – Input voltage up to 60 V DC (natural fast shutdown) to guarantee no risk of electrocution and fire on the roof.
• More powerful – MPPT at the module level to provide 10-30% more energy input from the sun compared to a string inverter.
• Smaller, lighter and easier – Smaller than a sheet of A4 paper, only 1.98 kg with integrated AC cable (1 m), easy installation by one person.
• More stable and reliable – Surge protection of 6000 V, MTBF (mean time between failures) >550 years, annual failure rate <0.18%.
• Better return on cost (IRR) – Extremely low failure rate, longer life (starting voltage only 22 V), low LCOE (levelized cost of electricity) over a long period (more than 20 years) of investment.

• Maximum efficiency of 96.7%
• Input voltage range 16 to 60 V
• Overvoltage protection of 6000 V
• Ambient temperature range: -40 + 65 degrees C
• External antenna to enhance communication with DTU
• Adjustable power factor
• Passive cooling, without fan
• No typical inverter needed at the end of the chain

Operation and installation:

• Easy assembly and disassembly
• Mounting directly under the panel
• Networking without the need for tools
• Barcode stickers to identify devices in the installation
• LED status indication on the housing
• Communication via WiFi, 2.4 GHz range
• Degree of protection IP67
• Dimensions 164 x 182 x 29.5 mm

Usage:

• Monitor the operation of each panel separately via the internet
• Very low failure rate
• High efficiency, minimal losses
• Maximum safety, low DC input voltage
• Noiseless operation
• Standard warranty 12 years, extendable to 25 years

NOTE: Microinverter works only with panels whose maximum voltage (Voc) does not exceed 60 V.
