3- Divide the battery capacity after DoD by the battery''s charge efficiency rate (lithium: 99%; Lead-acid: 85%). Power required to charge the battery = 300 ÷ 85% or 300 × 1.15 = 345wh 4- Divide the battery capacity value (after charge adding efficiency factor) by the desired number of charge peak sun hours.
The fundamental approach involves understanding the nominal voltage and capacity of the battery. The formula for lead-acid battery kWh is: markdown kWh = Voltage x Capacity (in Ah) It’s crucial to consider the efficiency factor when calculating to enhance accuracy.
If you want enough power for 3 days, you'd need 30 x 3 = 90 kWh. As discussed in the post above, the power in batteries are rated at a standard temperature, the colder it is the less power they have. So, with batteries expected to be at 40 to supply 10 kWh, with this data you'd multiply by 1.3 to see you would need 13 kWh of batteries.
Unlike LiPo batteries with have a maximum current rating, the lead acid battery only stated the "initial current", which is used for charging. The label stated not to short the battery. Hence, may I know what/how to find out the safe current to draw? How will the battery fail if I draw too much current (explode/lifespan decreased/?)? Thanks
