Q1:What is MPPT?
A: An MPPT (maximum power point tracker) is an higher efficient electronic DC to DC converter that optimizes the match between the solar array (PV panels), and take the voltage output from solar panels and convert them to a more suitable voltage to charge a battery bank. The maximum power point (MPP) is the ideal point on an IV curve where current and voltage multiply to provide the maximum power that the given PV system can produce at a given moment. To put it simply, they convert a higher voltage DC output from solar panels (and a few wind generators) down to the lower voltage needed to charge batteries.
Q2: How is the shipping arranged if I order sample/ trial MPPT solar controllers from SOPOWER?
A: We can ship to any country in the world even you only order 1 unit of our inverter. Inverter will be shiped either by EXPRESS,such as DHL, FEDEX, UPS, TNT etc., which arrived in about one week, or shipped with more economical way - by SEA.
Q3: How long will it take after I order the MPPT charge controllers?
A: If there are in stock, we will arrange the shipping within two working days after payment arrived in our account. The total delivery period depends on the shiping ways you select.
If without any stocking, it takes about 10-25 working days for producing.
Q4: What is the warranty of the MPPT solar controller?
A: 1 year.
Q5: Can you accept OEM, ODM service?
A: Yes, we could make inverter with your own logo and drawing.
