12V, 24V & 48V Solar Power Systems Compared. Pros & Cons

[Ndindu]

Again this all boils down to size and intended use. Selecting the right voltage for your solar power system is a critical decision that significantly impacts its overall performance. Whether you are powering your home, farm, or a commercial space,

In the long run 48V is cheaper to install and run

[hakimoto]

The higher the voltage the better

Higher voltages less current for a given wattage meaning thinner and less power losses along the wires.

Can a full 48v battery power 300l chest freezer, 1 pc and 6 led tube bulbs for 10hours?

Leta Wattage rating za hiyo freezer za LED lights nikufanyie hesabu ya load

Depends on inverter size.

Rule of thumb:
12V = upto 2,000W
24V = 2000 - 3000W
48V = above 3000W

Bulbs ni @ 48w, freezer 250w, pc sijui

12v is cheaper overall. All appliances za DC ni 12v. Also you can easily get 12DC inverter kwa duka.

@mr_shairman

…hest freezer, 1 pc and 6 led tube bulbs for 10hours?

Depends on the total KWh stored in the battery

…12v. Also you can easily get 12DC inverter kwa duka.

Hizo system za 48V pia ziko na outlet ya 12V na USB kadhaa za 5V/2A and 5V/1A built-in Kwa controller.

Small DC loads such as lights unanga directly Kwa DC out. No inverter needed.

48V is fed to the inverter for AC convention

48V unatumia solar panels ngapi?

[Ndindu]

@cortedivoire

…o install and run

48V unatumia solar panels ngapi?

Depends with the load, sometimes just 2 to 3 300W panels are just enough

Four wired in series

Are you planning to upgrade from 24V to 48V? Mimi am happy at 12V.

Mimi I am planning to go for 48v system but nitabuy indiviadual batteries za 12v then niweke into series That means going fully AC hadi kwa lighting. But for Kenya in general 12v system is enough. Kenya hawajafikia level ya kuconsume lots of power.

Could you advise on a good replacement for 200AH (2 pcs, 12V e-Solar) lead acid solar batteries? I’m toying with the idea of replacing with Lithium. What’s your take in terms of service, longetivity, and cost?

[hakimoto]

@Lionheart

…our take in terms of service, longetivity, and cost?

[Madenigiani]

I prefer the 12v system personally planning to upgrade to 1.5kw system for a 300w system

Going 48V will mean getting a 48V inverter = 60k. The batteries will cost you about 120k. Plus 48V charge controller = 15k. So about 200k. Switching to 48V sio mchezo especially when your 12V is still working well.

…hezo especially when your 12V is still working well.

Get an inverter with built in mppt charge controller.
