# microsol-apc(8)

Driver for APC Back-UPS BR UPS equipment

## NAME

microsol-apc - Driver for APC Back-UPS BR UPS equipment

## SYNOPSIS

**microsol-apc** -h

**microsol-apc** -a *UPS\_NAME* \[*OPTIONS*\]

**Note**\

This man page only documents the hardware-specific features of the microsol-apc driver. For information about the core driver, see [**nutupsdrv**(8)](/nutupsdrv/8.md).

## SUPPORTED HARDWARE

This driver supports the following UPS models:

• APC Back-UPS BZ1500-BR

• APC Back-UPS BZ2200I-BR

• APC Back-UPS BZ2200BI-BR

In 2009, Schneider Electric acquired Microsol Technologies, and by 2012, the entire Microsol line was being sold under the APC brand. This driver supports these newer, APC-branded models. Older equipment should use [**solis**(8)](/solis/8.md).

## EXTRA ARGUMENTS

This driver support the following extra optional settings in the [**ups.conf**(5)](/ups.conf/5.md).

**battext=***n*

Default = 0, no extra battery, where n = Ampere\*hour.

**prgshut=***n*

Default = 0, no programmable shutdown; 1 to enable one.

## COMMANDS

**shutdown.return**

Shut down in .3 minutes and restart in .3 minutes after that.

**shutdown.stayoff**

Shut down in .3 minutes and do not return.

## ISSUES

For other APC-Microsol models, the reported voltages, currents and power will be incorrect, as the communication protocol reports unprocessed data instead of real values, needing model-specific post-processing by the driver. Monitoring of UPS state (on-battery/on-line, critical battery) should work for other models, but is untested.
