HUGO Battery Backup for Tankless Hot Water Heater & Gas Appliances L30 No Flow Kit

I connected this to a new Navien NPE-240A2. For a few weeks it worked great and then suddenly the Hugo it started spontaneously and repeatedly rebooting which of course caused the Navien to also repeatedly reboot. Even worse I have tried everything to contact Safeguard Power Solutions - I called them (left voicemails), emailed them, submitted their webform. They are totally unresponsive - its as if there is no one alive at that company. On paper this is a great solution. Easy to install and just solves the problem. But in practice is is a pile of garbage. It is entirely possible there is a work around to what I am experiencing (at worst I have a defective unit) but I have no way to diagnose if they aren't available to contact. Note that I have carefully read their manual (and on device notices) and scoured their website - there is no mention of what I am seeing. I tried to make this work but SPS has left me hanging. If you try buying one of these just be sure to monitor it carefully for the first 30-days so you can return it via Amazon if it goes belly up as mine has apparently done. Not good. Hopefully another manufacturer will ship a comparable product to use in the future - one that actually works and has someone available to help troubleshoot if there are issues.

A little pricey, but installed easily and appears to be doing what it was designed to do. Provides backup power to keep water heating when the power goes out and also enables the tankless heater to keep the parts warm when power's out in the winter. A must have IMHO.

This unit failed after one month. I cannot get anyone to answer the phone in service or sales. I left multiple messages with no response.

We bought this particular item on the recommendation of our plumber who installed a tankless water heater. This will allow for hot water even in a power outage. We self installed the unit, not difficult. One important thing is that the outlet that you plug in your tankless into the unit is not easily visible, it's located up under the top area in the panel opening (unscrew the panel as directed and then feel up under that space). All other directions went as described in the manual. Took about 19 minutes to install. We placed ours on a rubber stool to keep it off the floor.

Been 2 months trying to get customer support to help me with my unit. It beeps randomly all hours of the day and night. I’ve tried all the troubleshooting steps they have provided. Amazon nor safe guard power solutions will do anything. Stay away! This used to be a great product as I’ve purchased them in the past. They no longer are the same company.

Does not work - plain and simple. Unplug from the wall, it does not kick on. Support line is always "leave a message" and they never return calls. This unit is too expensive for that type of poor customer support.
