12V and 24V solar panel systems are still the most commonly used, but 48V batteries are becoming prevalent. If you want to buy a 48V battery, you have to use the right solar panel sizes and voltage to get the best charging time. Three 350 watt solar panels connected in a series can charge a 48V 100ah battery in a day.
To charge a 48V 200Ah lithium battery, you typically need 8 solar panels rated at 250W each, assuming optimal sunlight conditions of about 5 hours per day. I want to explain more about how I decide on these figures. I have seen different systems with varied panel choices.
For instance, a 48V 100Ah battery has an energy capacity of 4.8kwh (48V×100Ah=4800Wh=4.8kWh). To charge it in 5 hours of sunlight, you''d need a 960W solar array (4800Wh / 5h). However, accounting for an additional 25% inefficiency, you would need a 1200W solar array to charge it effectively.
Three 350 watt solar panels connected in a series can charge a 48V 100ah battery in a day. For cold areas, the panel VOC should be between 67 to 72 volts, and for hot conditions it should be from 80 to 82 volts. An MPPT charge controller works best for 48V systems.
