1. Introduction
1.1 Product Introduction
SWF850 is an all in one PV analyzer that acts as a data collector by connecting to devices that exist
in a typical Solar Energy generating facility. Inverter protocols are read through the Ethernet or
Serial port and events or data will be processed by SWF850 and the SolarWise Cloud Server.
SWF850 has the following key features:
AI/DI/DO interface for sensor measurements and calculations
Serial and Ethernet port for communication with other device
LCD Display and keys operation
Linux Embedded WEB server with built-in WEB not requiring Cloud service
Configurable Settings for connect to Cloud service
Alarms sent via Email to plant operators let's farm owners to have a peace of mind on plant
operations availability.
Image of the actual SWF850 is shown below.
1.2 Unpacking and Inspection
Before begin operations, ensure the device is free from visible damages such as cracks, missing
connectors or chipped parts. All products are carefully checked by Enerwise Solutions before
shipping, however, it is possible damages are incurred during shipment.
Any visible defects should be reported to your dealer or Enerwise Solutions contacts, please use
original packing when shipping back the products.

2. Hardware Structure & Installation
2.1 Hardware Walkthrough
SWF850 have the following features in hardware：
1. Utilize ARM CPU processor and built-in 128 MB SDRAM with embedded Linux which provide
strong ability in communication data operation and processing
2. Built-in 256MB NandFlash for storing 10 years of data.
3. Two 100M Ethernet interfaces for accessing local network and remote network simultaneously.
4. Two serial ports, each COM port can access up to 32 peripherals for the inverter or SWF812
array box.
5. Six analog inputs for connecting with sensors, such as irradiation, temperature, wind speed,
humidity.
6. Six digital inputs for connecting with remote sensors of SPD or MCCB to monitoring the
equipment status; they also can be used as input of energy pulse from electricity meter.
2.2 Installation Safety Pre-Cautions
Note1：Damage due to in correctly connected cables!
All interfaces of SWF850 have fixed connection method, if cables are connected
incorrectly, this can damage or destroy the measuring and the device.
Connect cables only to the correct locations.
Ensure the correct polarity of the cables being connected.
Note2: Damage due to over overvoltage or overcurrent!
The SWF850 has a rated tolerance for each input types, each tolerance level is different
depending on the input type, it is absolutely necessary to double check the specifications
of each input to avoid damage.
For AI1 to AI4, the maximum input current is 20mA, if exceeded, will damage the input
interface.
For AI5 to AI6, the maximum input voltage is 5V, if exceeded, will damage the input interface.
For DI1 to DI6, the maximum input voltage is 30V, if exceeded, will damage the input interface.

2.4.5 Connecting to an External Revenue Meter
SWF850 has the ability to collect external energy pulses from revenue meters of 3rd party. These
pulses are called “Kt” pulses which usually one pulse represents a certain amount of kWh measured
in the meter. Hence, by collecting such pulse from the meter will allow SWF850 logger to cumulate
the actual energy measured by this meter. Below shows the digital input DI connector image:
With digital input specifications in the below table:

To complete the Kt pulse setup of the energy meter, please goto section 4.12.1.7.3 under DI setting.
IMPORTANT: For installations that do not have such meter installed, or do not have pulses
available, it is necessary to goto the software setup to link the total energy kWh data to the
inverter energy data, instead of a real meter. For this procedure, please goto section
4.12.6.1.
2.4.6 Connecting to the Digital Output (DO)

2.4.7 Connecting the Ethernet
SWF850 has two 100M Ethernet interfaces, they have their own MAC addresses and IP addresses.
User can check the IP address by LCD and set the IP address by the buttons on the button panel.
For further information about LCDs and buttons are described in Chapter 3.
2.4.8 Connecting the COM
SWF850 has two separate COM interfaces; the isolation of the COM is 500VAC, 1 min.
The two COM interfaces adopt RJ45 connector, COM1 is independent RS485 interface, COM 2 is
RS485 and RS232 mixed interface. Specific definitions for COM1 and COM2 are shown as below:
For COM2, RS485 and RS232 cannot be used at the same time; otherwise, can lead to
communication conflicts. The RS485 parameters of the interfaces are shown as follows:
Max Wire Length 1000 m
Max Connected Devices 32 Devices
Supported Baud Rates 4800 - 38400bps
Isolation Optically Isolated
Isolation Capability 1000VAC, 1min.
2.4.9 Powering up and Checking for Status LED
Before powering up, double check one final time the wire connections and the pin positions to see if
wrong pins are used and loose connections exist. Check also if ground connector is connected to
the ground terminal inside the array box. Ensure the voltage input being measured is well within
24VDC +10% ranges before powering up.
After power up, the RUN LED light will flash green each second to indicate device is ON and
running firmware. RX and TX LED lights will flash red and yellow respectively upon serial
communications. Alarm LED is lid when there is an alarm set point of SWF850 triggered in the
system, this may sometimes be due to incorrect AI alarm setting used so that over or under set
points are triggered.
