1.0 Introduction
This guide outlines the recommended settings and establishing communication for operation of one or more Any-
Grid™ PSW-H-5kW-230/48V, PSW-H-5kW-120/48V or PSW-H-6.5kW-120/48V hybrid inverter chargers with Arco
Invincible III battery modules in the low-voltage (50.4 Vdc nominal) configuration, referred to in this guide as “battery
modules”.
Note that the charge/discharge settings are automatically negotiated with the battery if this guide is used and
cannot be changed. If you wish to manually set these settings, then a communication cable between the PSW-H and
batteries is not needed and the battery type in settings menu 05 of the PSW-H must be set to “User defined” (USE). In
this case it is your responsibility to choose settings within the specifications of the battery to preserve the battery
warranty.
The Any-Grid must be installed according to the Any-Grid “User and Installation Manual” included with every Any-
Grid unit and available online at www.phocos.com. The battery terminals of the Any-Grid must be connected to the
batteries according to the Arco installation manual at the appropriate step mentioned in the chapter “5.0 Battery
Settings and Communication Cable Installation” of this manual.
WARNING: Be sure to read and respect the warnings in the installation manuals of the Any-Grid, the battery
modules and any other connected equipment. The installation must be conducted by a trained professional.
2.0 Requirements
The following is required to proceed with this guide:
•Any-Grid PSW-H-5KW-230/48V, PSW-H-5KW-120/48V or PSW-H-6.5KW-120/48V
•Battery communication cable with only the following pins connected:
Any-Grid PSW-H side Arco battery side
Make sure the cable is correctly oriented between the battery and PSW-H unit when installing below.
WARNING: Do not use the inverter cable included with your Arco batteries. Wiring your own cable
according to the pinout above must be done at your own risk. Any damage to the PSW-H or battery
due to incorrect wiring, cable orientation or use of an incorrect cable is not covered by any warranty.

3.0 System Overview
4.0 Battery Sizing
To maintain the full battery warranty, each battery module should be sized not to exceed 40 Adc continuous current
(verify Arco manual for details). It is thus recommended to use at least 3 battery modules in parallel to deliver both
sufficient continuous current and peak current for a single PSW-H-5KW at full power. When using multiple Any-Grid
units, be sure to increase the number of batteries accordingly to sustain the required currents. Using too few
batteries per inverter may void your Arco battery warranty.
The batteries must be wired in parallel to form a single large battery bank when using multiple Any-Grids, with a
nominal voltage of 50.4 Vdc. All Any-Grids must be connected to a single battery array.
5.0 Battery Settings and Communication Cable Installation
CAUTION: Before connecting the battery modules to the Any-Grid(s), please follow the installation
instructions in this chapter step by step. The battery, AC input source, AC output loads and PV input must
remain disconnected until instructed otherwise.
Any battery-related settings made will be over-written if the communication cable is used. If you wish to manually
use settings at your own risk, then do not use the communication cable.
1. Make the battery communication cable as described in chapter 2. This cable is designed specifically for
connecting the Any-Grid PSW-H to Arco batteries.
2. Ensure the battery modules are all turned off.
3. Set the battery DIP switches as described in the battery manual, depending on the number and
arrangement of batteries used.
4. Ensure the battery modules are still turned off. Connect the Any-Grid(s) to the battery power (positive and
negative) terminals with the correct polarity.
CAUTION: If the correct polarity of the battery is not observed, the Any-Grid and the battery may be
damaged, this is not covered by warranty.
Connect the battery communication cable mentioned in chapter 2 to the master battery’s RS-485-1 port and
the other end to the Any-Grid’s BMS port. Take care to connect the correct cable ends to the battery and
Any-Grid:

5. Ensure the battery modules are wired as outlined in the Arco battery manual. Turn on the batteries:
6. Ensure the “ON/OFF” load power button of the Any-Grid(s) is in the ON position (depressed), but no loads are
connected:
The Any-Grid(s) should now be running, the display(s) on.
7. Apply the following setting on the Any-Grid to which the Arco battery bank is connected with the
communication cable. This setting refers to the Any-Grid manual, chapter Operation → Device Operation
Settings → Settings menus.
• Battery type
Menu 05: User-defined battery (“USE”)
8. Once the setting has been applied, exit the settings menu by pressing to return to the main view.
9. Activate the circuit breakers or insert the fuses to energize the various inputs and outputs on the Any-Grid in
the following order (skip any that are not connected):
a) AC input
b) PV input
c) AC output
10. If you are using more than one Any-Grid, this procedure ensures that the unit to which the Arco battery is
connected, will communicate with the Arco battery BMS. Automatically, the battery type of all other
connected Any-Grid units will be set to “User-defined”, this is normal.
The commissioning and programming of the battery-related settings of the Any-Grid is now complete.
