FAQs
Does the M5 charge batteries from the grid?
The M5 does not charge batteries from the grid, because PV is
a cleaner and more efficient energy source. Some other systems
use grid power to charge batteries, which means you are paying
the utility to maintain battery charge levels.
Can I share one battery bank with two M5 units?
The M5 today requires separate battery banks for multiple units.
A battery sharing feature may be introduced in the future.
Can I power 240-volt loads with the M5?
The M5 has a 120 Vac output rating. To run 240 Vac loads,
you can install a step-up 120-to-240 Vac autotransformer on
the load output or critical load subpanel.
Can I parallel two M5 units to provide 240 Volts
for back-up power?
Two M5's at this point cannot be combined to power a 240 Vac
load.
What capacity battery charger do I need to use with
the M5?
The M5 is an integrated power conversion system that includes
a built-in 100A battery charger. You do not need to add a
separate battery charger.
Do I need to install an inverter bypass switch?
The M5 has built-in bypass configuration capability. Bypass
instructions are printed right below the onboard AC disconnects.
What rating of DC disconnect for PV do I need with
the M5?
The M5 has built-in DC disconnects, including GFI (Ground
Fault Interrupt).
Is there a monitoring package available to observe
and analyze M5 performance?
We offer an optional Windows-based software package called
Smart Power Monitor.
What device do I need to install with the M5 so that
power is transferred to critical loads when the grid goes
down?
The M5 has a built-in AC transfer contactor that provides
back-up power within 32 ms if the grid goes down, so you do
not need to install any extra components.
