Can I connect multiple tankless water heaters to one HUGO?

Technically yes.  However, the maximum output of HUGO is 350W.  If the load exceeds this amount, HUGO will automatically go into protection mode and eventually goes into fault mode that would require a hard reset.  If the total output is below 350W, HUGO will be able to operate.  Please note that we recommend continuous run of the inverter at about 50% capacity to maximize life span of the product.

What is the difference between a modified sine-wave (MSW) and a pure sine-wave (TSW)?

TSW is a much more efficient inverter.  in some applications, it uses between 15-20% less watttage than a MSW.  MSW's may cause motors to become very hot and occasionally cause burnouts.  It may also cause damage to transformers because of its lack of efficiency. TSW systems are also more noise neutral without the sounds typically associated with MSW systems such as the humming of a fan motor.

Can I add additional batteries to my existing HUGO?

Yes, but you hardly need to. HUGO will provide 5-6 hours of hot water usage.  This is typically enough time for your city power to be restored with around 1-2 hours of actual hot water usage per day.  For those rare instances when the power may be off for a longer duration you can add a spare battery and connect it to the HUGO unit.  You can view the specification sheet to get battery information.

My water heater does not have a plug, how do I hardwire?

You can simply install a pigtail/plug to your water heater and plug it in to the unit.  You can also hard-wire your water heater directly to our inverter's terminal through the knockout hole on the under-side of the side panel.  Please ensure all power sources are UNPLUGGED  before attempting to do so.  Failure to comply to electrical codes and safety may result in hazardous situations.  If you feel uncomfortable with this procedure, please STOP and consult with a local certified electrical professional.

How do I check if the flow sensor is working or not?

In rare instances that the flow sensor fails to operate, it will not send a signal to HUGO to start providing power to your appliance.  To troubleshoot the status of the flow sensor, simply unplug the green 4 (four) pin connector in front of the inverter. This will bypass the flow sensor entirely.  If the HUGO starts to operate correctly, then the flow sensor has either failed or there is an issue with the installation of the sensor.  Please contact us or consult with your local HUGO dealer to further information.

Can I bypass the flow sensor and still have the temperature sensor?

Yes, simply unplug the green port in the middle of the inverter tray and connect a 'jumper' for the temperature port leaving the flow port unplugged.

Can HUGO be mounted in a salty/ocean environment?

Yes. HUGO can be installed in all climates.  It is completely sealed and all weather proof.

What is the life expectancy of the HUGO battery?

Typical battery life after installation is approximately 2-3 years in normal ambient temperatures.  Severe climates may shorten the battery life.

Is the flow sensor rated for outdoor installation?

The flow sensor should always be properly be jacketed to protect from harsh climates and direct sunlight.
