Four Steps To Designing An Energy Storage Or Off-Grid Solar System:
1.Before selecting or purchasing any equipment required for a hybrid or stand-alone power system, the installer should have a good understanding of the basics of sizing energy storage systems - The most important part of the process is establishing the load profile or building a load table to estimate the amount of energy required to be generated and stored per day. If you cannot develop a load table then a professional solar installer or system designer should be consulted. The general steps are as follows:

2.Estimate the loads - how much energy is required per day in kWh. For off-grid power systems, a load table should be developed for both summer and winter requirements. The surge loads, power-factors, and maximum demand or peak demand also needs to be considered when selecting the battery and inverter/charger.

3.Determine the battery size required in Ah or Wh. You need to take into account the battery type and chemistry, maximum depth of discharge (DoD), round-trip (charging) efficiency and maximum charge rate.

4.Determine how many solar panel/s are required to charge the battery and supply the loads taking into account local conditions such as - average irradiance throughout the year, shading issues, panel orientation, and temperature derating factors.

After steps 1 to 3 have been established you can now select the appropriate Inverter/charger, solar inverter/s or MPPT Solar Charge Controller/s to suit the system.

Q 6.How to pay for solar controller?
A:We accept paypal, western union, T/T. If you have any good payment, we also can accept.

Q 7.How to choose suitable inverter?
A:If your load is resistive loads, such as: bulbs, you can choose a modified wave inverter. But if it is inductive loads and capacitive loads, we recommend using pure sine wave power inverter.

Q8.How do I choose the size of the inverter?
A:Different types of load demand for power are different. You can view the load power values to determine the size of the power inverter.
