Frequently Asked Questions
What is the warranty?
OUPES power stations offer 5-year warranties. you can get a FREE 1-year warranty extension after warranty registration.
Does OUPES support pass-through charging?
Yes, all OUPES products support pass-through charging without damaging the battery.
What types of batteries does OUPES use?
LiFePO4 -- The battery retains over 80% of its original capacity after 3,500 cycles, with gradual performance decline thereafter. They last six times longer than ordinary lithium batteries and are safer, more stable, and eco-friendly, containing no harmful heavy metals.
Can two Mega be connected together to increase watt-hours?
Standard generators typically cannot be paralleled. None of the Mega, OUPES, or Exodus models support this function.
What is the recommended charge level for a battery or device before recharging?
It is recommended to allow the device to discharge naturally until a low battery reminder appears, and then recharge it upon receiving the reminder.
Is the 120 volt AC charging connector a standard IEC (D-type plug) connector or a proprietary connector?
standard IEC (D-type ) plug
How quickly can the Mega be fully charged after it is completely discharged?
The charging time depends on the battery capacity and the charging speed of your power station. We use the following formula to estimate the charging time:
Estimated Charging Time = (Battery Capacity / Charging Speed) * 0.85
Please note that this is only an estimate.
For example, to charge a Mega 5 with AC power (maximum charging speed of 1800W and capacity of 5040Wh):
Estimated Charging Time = (5040 / 1800) * 0.85 ≈ 2.4 hours.
Can I charge using a "briefcase" style solar panel with its own charge controller?
Yes, you can use a "briefcase" style solar panel with its own charge controller, provided that the current output from the controller is lower than 15A.
Does the battery backup have MPPT for solar charging?
The B2 backup battery has MPPT for solar charging, while the B5 backup batteries do not include MPPT (Maximum Power Point Tracking).
