Beginner here currently researching a new system. The current plan is to have 1,800 watts of panels charging 48-volt lifepo4 batteries. The existing ideal array mounting location (barn roof) is about 150ft from the likely battery storage location (with existing conduit in place). There is another cleared area that is closer (about 50ft) to the battery storage location but would require building a mounting rack. I understand the more distant location will require thicker wire if it's even practical at that distance but I am not sure what amount of voltage drop is acceptable.
Currently trying to weigh the pros and cons of running thicker gauge wire to the existing mounting location (if even practical) or building a new mount closer to the batteries.
Other background info: The battery storage location is about 125ft from the off-grid cabin which is to be powered with this system and is located in northern Maine with winter temps down to -25f. The cabin has a 240volt well pump.
