Frequently Asked Questions
What's the difference between the standard and (L) model?
The (L) model is specifically designed for extended runtime applications. It
has more robust battery charging circuitry and supports connection to external battery banks,
while the standard model is limited to internal batteries only.
Can I use third-party batteries with this UPS?
Yes, the UPS is compatible with third-party batteries as long as they meet
the voltage and capacity specifications. However, using manufacturer-recommended batteries
ensures optimal performance and maintains warranty coverage.
How often should the batteries be replaced?
Under normal conditions, sealed lead-acid batteries typically last 3-5
years. The actual lifespan depends on factors like environmental temperature, number of
discharge cycles, and proper maintenance through the UPS's battery management system.
Is this UPS suitable for solar applications?
While primarily designed for AC input, this UPS can work with solar systems
that provide stable AC output through an inverter. For direct DC solar input, we recommend our
solar-ready UPS models specifically designed for that purpose.
