About PWRcell Inverters

The PWRcell inverter connects to PV Link™ optimizers

and PWRcell batteries to form the PWRcell system for

grid-interactive solar-plus-storage.

Upon the loss of grid power, PWRcell inverters

disconnect from the grid and provide AC power to

support protected loads when configured to do so.

All PWRcell products use the REbus™ 380 VDC

nanogrid to connect to each other. The REbus nanogrid

automates the flow of power to enable plug-and-play

setup and operation of PWRcell equipment. For more

information about REbus, visit www.generac.com.

In Figure 2-3 PWRcell inverter (E) is directly connected

to PV Link optimizers (B) and PWRcell battery (C) on DC

(REbus) line (D). To the right of the inverter are AC lines:

120/240 VAC for grid and home loads (G) and protected

loads (H).

General Information

Inverter Control Panel

Figure 2-4. Inverter Control Panel

See Figure 2-4. The PWRcell system is controlled

through the PWRcell inverter control panel. The inverter

control panel is used for adjusting system settings and for

interacting with devices.

REbus Status LED

REbus Status LED (C) communicates REbus nanogrid

status through LED color.

•Green – all devices are functioning normally and

PV Links are generating power on REbus.

•Yellow – no PV Links are generating power from

PV on REbus.

•Red – one or more REbus device has a fault that

requires attention before operation will continue.

NOTE: A red LED can also indicate a fault with the

REbus wiring itself. See display (A) for more information

about the specific fault detected.

Inverter LED

Inverter LED (D) communicates the status of the utility

grid and/or inverter through LED color and state.

•Green – the inverter is enabled and functioning

properly in either state “grid connected” or state

“islanded.”

•Yellow – utility grid is not within normal conditions,

but user intervention typically is not required. The

inverter will restart as soon as the utility grid

returns to normal conditions.

•Red – a serious fault with the utility grid or inverter

has been detected and user attention is required

before the unit will resume operation. See display

(A) for more information about the fault detected.

•No light – the inverter is disabled or powered off.

Internet LED

Internet LED (G) is illuminated when the inverter is

connected to a router and has an IP address. See

Ethernet Configuration.

NOTE: A blue Internet LED does not mean that the

inverter has connected with the Generac server.

Shutdown Mode

NOTE: A loss of grid power will not de-energize REbus

in a PWRcell system configured to island with enabled

energy storage.

Shutdown button (E) activates a transition to shutdown

system mode. Disabled PWRcell equipment will limit

output voltages to a safe level for servicing.

To enter shutdown, press and hold shutdown button (E).

In shutdown mode:

•PWRcell inverter will stop sourcing power to

REbus, and immediately disable all communicating

power sources on REbus by sending a system-

wide system mode change signal.

NOTE: Successful signal transmission relies upon

proper configuration of PLM channels across REbus

devices (PV Links and Batteries).

•Shutdown LED (F) will illuminate.

•Inverter screen (A) will display REbus DC bus volt-

age and text indicting shutdown mode has been

initiated.

NOTE: The AC section of the inverter will still be

energized unless the building AC disconnect or main

service breaker is shut off.

6 Owner’s Manual for Generac PWRcell Inverter

General Information

System Modes Overview

Generac PWRcell offers several system modes for various installation configurations, markets, and applications.

Connected REbus devices work together to manage the distribution of power based on the selected system mode.

Some modes interact with PWRcell batteries to store power and/or balance production and consumption.

See Table 2-1 and Table 2-2 for an overview of available system modes.

Grid Tie

In Grid Tie mode, the PWRcell inverter functions as a

conventional grid-tied inverter system. The system

powers local loads and when generation exceeds load

demand, excess power is exported to the utility for net

metering and other credits.

NOTE: Grid Tie is intended for use with systems that do

not include a PWRcell battery. For systems where a

PWRcell battery will be connected at a later date, operate

in Grid Tie mode until the battery is installed.

Clean Backup

NOTE: Grid power is not used to charge batteries in this

mode.

See Figure 2-5. In Clean Backup mode, the inverter

prioritizes keeping the battery charged and ready for a

grid interruption using solar power only. If the battery is

not fully charged, the inverter uses all available solar

power to charge the battery.

See Figure 2-6. When the battery is fully charged, solar

power will flow to local loads and the grid.
