What are you running for surge and/or UPS/battery backup for your H2D. My 850va UPS is not handling high temps/power very well so I need a new one and the smaller one will be put on the A1 Mini. Whatcha got?

Cool. Thanks! I should have just resurrected that thread. It was somewhat helpful, seems the H2D is limited to 1500 watts in the US?

In the US, the peak is closer to 1600w, which occurs at the very start, and then it declines from there as it heats up. [Screenshot_20250414_025513_Emporia Energy] I think this screenshot was with the chamber heater off. Also, the hotter the heated bed, the longer the high power draw will take. …

Makes sense, hence why my printing ASA with my puny APC was screaming at me much longer than usual. I’m no electrician so all this insight is awesome, thank you!

I bought a used 3000va rack mount ups used for $175, put new batteries in it ($89) and now no longer have the dreaded 2 minute long beeeeeeeeeep while the h2d warms up. I did have to buy a 30amp to 15amp adapter so I could plug it into the wall. I have 15amp breakers and it hasn’t tripped one yet.…

Which UPS/battery backup system?

Bambu Lab H2 Series
