Run DC load with Easysolar?

I have an Easysolar 48/4000/150-70 waiting to be installed, and will run a Lifepo4 battery pack with REC BMS that connects to CCGX with CAN. I've understood this will give SOC and charge/discharge instructions to the solar control and inverter to avoid over/under voltage. However, I'd also like to run a 4G router on 9–30 VDC (max 7 watts) without the inverter running with high idle consumption (25 watts) and not risk running the battery low.

1. Is there anyway to pass through 48V through the Easysolar / Multiplus?

2. The Multiplus programmable relay supports 4A up to 35V (1A to 60V) - could I run the router on that relay alone?

3. If not, I assume I can use the Multiplus programmable relay to control a 48v relay (e.g. Crydom ED06D5 with a control voltage range of 5-15 DC) based on SOC (with a 48 to 12 converter)?

Why not just use a Victron dc to dc converter powering your router, running directly from the battery pack? The programmable relay is merely a switch and not capable of regulating voltages

Thanks, yes thought so in regards to the programmable relay.


Since I will be away for longer periods I want the DC load to shut down if battery is low for some reason.
