What should I do if the LED on the micro inverter is flashing slowly?

Flashing per 4 seconds indicates WiFi connected and inverter working. Other flash rates indicate different states: 1 sec = WiFi connected and AC on, 2 sec = WiFi connected and standby. Refer to the LED table in the manual.

Is professional installation required?

While the kit is designed for DIY, it is strongly recommended to have a qualified technician due to the weight (>20 kg) and electrical connections. Never install alone.

How do I clean and maintain the solar panels?

Regularly check screws and overall stability, especially after storms. Clean panels with a soft cloth and mild detergent if needed. Avoid abrasive materials.

Can I use this kit without grid connection?

No, this is a grid-tied system. It must be connected to the utility grid with prior approval from the utility company.

What is the warranty period for the Haier HMK1P-800D-FT420X2?

Warranty details are not specified in the manual; contact Haier customer service or refer to the product documentation. Modifications to the mounting kit void warranty.

2. Installation Instruction

STEP 1. Mounting Balcony Bracket

STEP 1.1 - Mounting the aluminum profiles on the solar panel

First, please connect the vertical profiles with the provided holes on the solar panel.

STEP 1.2 - Mounting the triangular bracket

Use M8 screws to connect the triangular bracket. (Attach the Aluminum profile first, then the Rail connector) The suspension angle of the PV module can be adjusted through different holes.

STEP 1.3 - Mounting the crossbar

The crossbar gives the additional stability of the substructure and is usually used to mount the micro-inverter directly.

Pretighten the M6 screws and slider, then slide the slider into the crossbar, finally tighten the M6 screws and slider. Repeat the above operation to fix the crossbar.

When doing so, observe the required cable lengths. Depending on your local requirements, you can mount the crossbar in different positions. (The lower the installation position, the better the stability).

STEP 1.4 - Installation of Microinverters

Please use 2 x M8 screws (for micro inverter) on the crossbar to fix the inverter.

Before installing the micro inverter, record the information on the label on the microinverter. (required for subsequent distribution)

Follow the procedure 1.1-1.3 to install another set of brackets

CAUTION

Before installing the microinverter, record the information on the label on the microinverter (required for subsequent configurations)

STEP 2. Connect the DC Cable with Micro Inverter
