I am installing 24v heated floors in our 40ft motorhome. They will pull a max of 1800watts at powerup, and drop to about 1100 watts after the floors are at temperature. I need to run two separate circuits of 900watts each to the control units (1 circuit to each) with a distance of about 20feet from the power supply center.
Here is my setup:
My questions:
1. What size wire do I need to run the 20ft from the Orions to the controllers (24v, 37.5A )
2. What size wire do I need to run the 5 ft from the Lynx Distributor to the Orions (12V, 75A)
3. I have heard that it may be better to run the positive from the most distant battery in the series (battery the negative is connected to) rather than from the Lynx Distributor due to the wattage draw on the system, any thoughts on that?
4. I plan to add a second multiplus, but should I do it sooner than later due to the wattage draw of the floors? Our microwave, airfryer, refrigerator, etc. all run on the inverter circuit but rarely draw more than a five hundred watts at a time unless we are using everything at once.
Thanks in advance!!
Here is my setup:
- 1 12/120 3000 Victron Multiplus II
- 6 206Ah SOK 12v batteries
- approx. 1650 watts Solar (will be expanding to 2k)
- Batteries connect to Lynx PowerIn, then to Lynx Smart Shunt, then to Lynx Distribution Hub which connects to MultiPlus, MPPTs, and 12v House Load.
- I have two Orion 12/24 50A, one for each floor circuit to increase the voltage from 12 to 24.
