Solar Batteries Explained

Capacity, voltage, chemistry, depth of discharge and why storage often dominates small off-grid design decisions.

Battery planning revolves around usable energy, voltage, discharge limits, charge rates, temperature and cycle life. Chemistry changes the operating envelope and safety requirements.

Capacity is not runtime by itself

Runtime depends on usable watt-hours and actual load, with conversion losses and reserve margins included. Follow the battery and battery-management-system documentation.
