# solis(8)

Driver for Brazilian Microsol SOLIS UPS equipment

## NAME

solis - Driver for Brazilian Microsol SOLIS UPS equipment

## SYNOPSIS

**solis** -h

**solis** -a *UPS\_NAME* \[*OPTIONS*\]

**Note**\

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

## SUPPORTED HARDWARE

This driver has been tested with:

• Solis 1000 VA

• Solis 1500 VA

• Solis 2000 VA

• Solis 3000 VA

• Back-UPS BZ1200-BR

• Back-UPS BZ2200BI-BR

All Solis models are sinusoidal on-line.

In 2009, Schneider Electric acquired Microsol Technologies, and by 2012, the entire Microsol line of equipment was being sold under the APC brand. Newer devices may be better supported by [**microsol-apc**(8)](/microsol-apc/8.md) driver instead.

## 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

The APC version of the Microsol protocol is slightly incompatible with the **solis** driver. As of version 0.62 of the **solis** driver, the driver will connect to the UPS, but some values are read incorrectly.
