Hydrogeneration
Charged by solar panels
Powered by third-party batteriesQ: What is hydrogeneration？
A: The hydrogeneration’s mechanism is very similar to hydropower. When sailing, the force of water can be imposed on the propeller rotation, and then leads to the motor running. Therefore, the battery would be charged, and the power would be stored.
Q: Under what condition the hydrogeneration feature can be activated?
A: The triggering of the hydrogeneration function requires the following conditions:
- Users need to use ePropulsion Evo series motors and ePropulsion battery, applying with the communication cable. ePropulsion’s folding propeller does not apply to this feature.
- Place the Evo control in a neutral position, and turn on the hydrogeneration function in the control setting. (On by default)
- The motor remains in a power-on state.
- ePropulsion battery power level is below 90%
- When sailing to the speed between 4-19 knots, the motor would be able to generate the electricity, and the power can be stored. After 19 knots, the hydrogeneration function would automatically turn off.
Q: Can I charge the Spirit Plus battery with a solar panel while still using it?
A: Yes, you can charge the Spirit Battery and Spirit Plus Battery while using it.
Q: Can I use 3rd party solar panel to charge the Spirit battery? What kind of specs should I look into?
A: Yes, you can use the 3rd party solar panel but you would still need to use eProprolsion solar charge controller. For the solar panel, the maximum operating current is 10A; the operating voltage should between 12V ~ 35V.
Note: Using 3rd party solar panels is not recommended for warranty reasons.
Q: Can I use ePropulsion solar panel or 3rd party solar panel to charge the E-Series battery?
A: The ePropulsion solar panel was designed for the Spirit batteries, it is only compatible with the Spirit 1.0 battery and Spirit Plus battery.
To charge the ePropulsion E-Series Battery with only 3rd party solar panels, users need to set the solar charger float voltage to 57.6V. Meanwhile, the solar charger maximum discharge current needs to be less than 20A/40A/75A for the E40/E80/E175 battery collectively. Otherwise, the E-Series Battery would not be charged.
Q: Are ePropulsion motors compatible with 3rd party batteries?
A: Yes, ePropulsion products can use the 3rd party compatible batteries, including the EFOY battery. It provides reliable onboard power supply for ePropulsion motors whenever needed and helps extend the runtime and range to allow you to have more fun on water.
Q: To charge the ePropulsion motor with a 3rd party battery, what specs are required? What else needs to know?
A: For the 3rd party batteries specs, the nominal battery rated voltage should be 48V, and the continuous discharge current should be over 62.5A (Navy 3.0 Evo and Pod Drive 3.0 Evo), and 125A (Navy 6.0 Evo and Pod Drive 6.0 Evo). To ensure at least one hour duration, the battery capacity should reach at least 3000Wh or 6000Wh.
When powered by 3rd party batteries, the ePropulsion motor cannot access the real-time battery status nor apply the best operation strategy.
If any malfunction occurred due to the 3rd party batteries, the warranty would not apply.
