1. Required capacity considering runtime
$$ \text{Capacity(Wh)} = \text{Load power(W)} * \text{Runtime(Hr)} $$
2. Recalculating capacity considering Depth of Discharge(DoD)
$$ \text{Capacity(Wh)} = \text{Capacity(Wh)} * \frac{100}{\text{DoD}} $$
3. Recalculating capacity considering converter efficiency
$$ \text{Capacity(Wh)} = \text{Capacity(Wh)} * \frac{100}{\text{Efficiency}} $$
4. Recalculating capacity considering safety margin
$$ \text{Capacity(Wh)} = \text{Capacity(Wh)} * ( 1 + \frac{Margin}{100}) $$
\[ \boxed{ \text{Energy Required} = \text{Capacity(Wh)} } \]
5. Required Battery capacity for the given battery voltage
\[ \boxed{ \text{Battery capacity(Ah)} = \frac{\text{Capacity(Wh)}}{Voltage(V)} } \]
