General Information

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.

Figure 2-5. Clean Backup (1 of 3)

Figure 2-6. Clean Backup (2 of 3)

See 

Figure  2-7

.  When  grid  service  is  interrupted,  the

system  enters  Islanding  mode.  In  Islanding  mode,

protected  loads  are  supported  by  solar  and  battery

power. If enough solar power is available, the solar will

simultaneously charge the battery and support the loads.

Figure 2-7. Clean Backup (3 of 3)

Priority Backup

In Priority Backup mode, the inverter prioritizes keeping

batteries  charged  and  ready  for  grid  interruption  using

solar or grid power. If the battery is not fully charged, all

available solar power is used to charge the battery. When

the available solar power is lower than the battery input

power  rating,  the  inverter  uses  grid  power  to  expedite

battery charging.
See 

Figure  2-8

.  If  solar  and  grid  power  are  available,

both  can  charge  the  battery.  The  system  displays  the

amount  of  power  being  drawn  from  the  grid  and  the

amount of power being consumed by local loads before

reaching the battery.

Figure 2-8. Priority Backup (1 of 2)

See 

Figure 2-9

. In the event of grid failure, the inverter

enters Islanding mode. Protected loads are supported by

solar  and  battery  power.  If  enough  solar  power  is

available,  the  solar  simultaneously  charges  the  battery

and supports the loads.

Self Supply

NOTE: 

This feature requires CTs to be properly installed

and calibrated prior to use. For more information on CT

calibration, see the PWRcell Inverter Installation Manual.
In  Self  Supply  mode,  the  inverter  prioritizes  powering

local  loads  using  solar  and/or  stored  power  first.  This

mode  is  optimal  in  markets  where  net  metering  is

unavailable or unfavorable, making battery-stored power

more economically attractive than grid-provided power.
See 

Figure 2-10
