Low charge rate
Any
charging
source
Charge complete or nearly
complete
Check DC voltage and charging stage.
High temperature
Performance is derated in higher temperatures.
Allow SkyBox to cool, or apply external cooling.
High loads
If total loads and charging exceed the AC input
and PV sources, the charge rate decreases to
give priority to the loads. Turn off some loads and
test the charging rate again.
Will not charge
Generator
source
Requires minimum 4 Aac load
before charging can occur
Apply load to SkyBox.
Will not use generator to charge if
PV power is already charging
No action required.
No AC output, will not
accept AC input

Unit turned off
Make certain the

button is set to ON.
Rapid shutdown has occurred
Check
ALERT
messages and Rapid Shutdown
Initiator.
No
batteries
AC source does not meet
requirements
Check the AC source (voltage, frequency, and
other factors).

Check the AC source (voltage, frequency, and
other factors).
Generator
source
Grid source is present
SkyBox will not connect to the generator if grid
is present.

Connection timer is still running
Wait for timer to expire (

Programmed disconnection (due to
time of day, operating mode, or
other priority)
Adjust programming as needed (requires login).
Will not sell
Grid
source
Batteries still charging
SkyBox will not sell while the charger is active
and all available solar power is used to cover
the loads and charging. Wait until the charge
cycle is complete, then try again.
Reduced selling
Grid
source
Sell limit
set too low
Adjust setting as needed (requires login).
Power used for other purposes
Power must supply loads (self-supply) and
batteries before being sold. Check loads and
all
T i l e
readings.
Limited PV size or conditions
Check solar conditions or PV voltage.
High temperature
Performance is derated in high temperatures.
Allow SkyBox to cool, or apply external cooling.
Loads interrupted upon
transfer
AC source
(grid or
generator)
Erratic AC source voltage
Check input AC voltage. If not consistent, the
problem is external. AC source voltage may
have dipped to a low enough point to disrupt
loads before the inverter could take over.
Loads are sensitive to transfer time
SkyBox features a small but noticeable response
time during transfer. Some devices may require
an uninterruptible power supply (UPS). Consult
the manufacturer of that device for backup
power requirements.
Loads are too large
SkyBox can pass through more power than it can
invert. Reduce load size.
Undersized battery cables
Battery cables smaller than recommended will
cause a significant voltage drop when switching
to batteries, acting like either an overload or a
low-voltage condition. Size all cables correctly.
