Before configuring a solar system solution, customers are required to provide the following information:

(1) How much eletricity consumption kwh do they need consume monthly/daily? ---in order to calculate out the solar panel quantity.

(2) How much peak working power of all loads? -- in order to configure the rated power for the solar inverter.

(3) How many hours do the load need work after sunset? -- in order to configure the capacity for Lithium battery.

Based on experience and the budgets of many customers, Generally, the minimum capacity of lithium batteries is configured according to the discharge rate of 0.5C.
