connected to the RS485A/RS485B of the next inverter.

Connecting RS485 Terminal Resistance

When RS485 link communication is abnormal, connect a 120
terminal matching resistor between RS485A and RS485B of CH1000 and
the inverter at the end of the daisy-chain.

Connect the Meter

Connecting the meter communication cable using shielded twisted
pair cable, RS485A1/B1 of CH1000 to connect RS485A/RS485B of the
meter respectively.

Connect the Meter CT and Power Line

For a single inverter, connect the meter CT and power lines with
the CT direction pointing from the inverter to the grid.

WIRING

ATTENTION
Please disconnect all power supplies before wiring and pay attention to safety during wiring.

(1) RS485 Wiring (Cable preparation: shielded twisted-pair cable with a cross- sectional area of 0.75mm² to 1.5mm² and a communication line length of no more than 1,000m)
Connect the inverter (Depending on the situation, it may be necessary to upgrade the inverter version first) Single inverter connection: RS485A2/B2 in CH1000 are connected to RS485A/RS485B in the COM port of the inverter respectively. The COM port pins are shown below, where PIN1/PIN2 are RS485A and PIN3/PIN4 are RS485B.

è`Fix the expansion screws and expose the wall surface about 6.4 mm. mount the CH1000 on the screws.

NOTICE
The meter should be installed in the distribution cabinet or box, not exposed. Currently supported meter models are Chin meters (DTSU666, DDSU666), which need to be used with CT. Users are requested to prepare their own CT with current ratio of 1-9999, no model requirement, and choose the appropriate aperture according to the wire diameter at the convergence of the inverter. Refer to the operation manual of the meter for the method of connecting CT wire and power wire at the meter end.
(2) Antenna and SIM card Installation Installation of Antenna Tighten the corresponding model antenna against the antenna connector on the CH1000, and then rotate the antenna handle by 90°
Installation of SIM card For SIM card, please prepare your own large industrial grade card that fits the slot size (25mm x 15mm x 0.76mm) of this device. Please power off the device first, judge the direction of SIM card installation according to the silkscreen of the shell, and press it until the SIM card locks tightly.
