Hello Solaristas! I'm installing a 48v system over the next few weeks and need some advice about Power over Ethernet (PoE). This is for an off-grid vacation cabin.
My battery bank will be a 48v bank, and I'm planning to power always-on cameras and some Raspberry Pis for weather and power monitoring, security, and irrigation control. Since all that stuff runs well off of PoE and everything is DC, I figure why take the hit of having the inverter always being on, and just use PoE for the always-on gear.
I'm having a heck of a time finding equipment to power 48v active PoE (802.3af) directly from 42-56v that the battery bank puts out. Curious what others have done here? I may try out a Victron 48/48-Volt converter, but I'm not 100% sure that's the best fit for my application. Can PoE equipment handle the 42-56v actual battery voltage without the need for a converter? If so, I'll happily save a bit.
Perhaps I'm worrying too much about the loss from having the inverter on full time? Curious what others think.
