Operation
4.12 Operating Confi guration - Standalone vs Networked
The operating confi guration in the PT-100 controller uses default settings that are adequate for
most installations (shown in Table 4-3 and described below). When the controller is confi gured
as a standalone controller, the controller’s internal DIP switch is used to adjust these settings.
However, when confi gured as a networked controller, the optional remote control/display (with
PT-100 menus) allows more adjustable settings and wider adjustable ranges. For information on
these settings in the remote control, refer to the remote’s owner manual.
Some of the adjustable operating parameters:
• Battery Type: Sets the type of batteries being used in the system. This information tells
the charger what absorb, fl oat and EQ (if allowed) voltage levels to use to charge the
batteries; and the amount of time the batteries are held at the EQ voltage.
• Absorption Done: This setting allows the user to determine how long to charge the
batteries in the Absorb charge stage. This can be based on time (default), return amps,
or State of Charge (SOC).
• Max Charge Rate: This setting can be used to limit the amount of current that the
charger can deliver to the batteries.
• AUX Relay: Sets the condition that causes the relay to engage, either from a controller
fault or a battery voltage level.
Note: Using a networked remote control allows you to monitor and customize the operating
parameters for your PT controller; such as viewing daily peak power levels, viewing power harvested,
viewing fault history information for troubleshooting, viewing control charge stages, and much more.
Info: The controller uses the remote settings when networked, and continues using these
settings even if the remote is disconnected

. These settings are retained until all power (PV
and battery) is removed, then the controller reverts back to using the DIP switch settings.
