Hi,
I'm planning on building a semi-offgrid system in my future shed that i'm building next year, and i'm already trying to plan a bunch of stuff in advance.
One thing i'm not sure about however is if i should go for a 24V or 48V system.
The pro's of the 48V system
- Amperage divided by 2 so thinner wires required (at todays copper prices)
- Solar charge controllers can deliver higher wattage for the same price, or you can use a cheaper model for the same wattage (using victron datasheets as reference)
The con's
- Way less hardware that supports 48V
- You need 16 batteries in series (not really a big con)
- More expensive because less hardware to choose from (somewhat, because of the lower amperage you can save some money on other things)
What are your opinions? Knowing that the system will have to power 4-5Kw
