Technical FAQs 4

How many strings can be connected to a solar inverter?

Here are the results we calculated: This inverter has 2 MPPT trackers, so a total of 2 strings can be connected to the inverter. We know that there can only be 13 modules maximum installed. We can have one MPPT with 6 modules in a string and the other at 7 modules in a string. Check out UpTop Solar String Sizing Tool that does this for you!

How many strings can a CPS 60kW inverter have?

For example, the CPS 60kW string inverter has 15 inputs and 3 MPPTs allowing for 5 strings to be connected to each MPPT. Let’s assume we’re using 5 strings of 15 modules, 5 strings of 16 modules, and 5 strings of 17 modules all connected to the same inverter.

How many modules can an inverter connect per string?

Considering the local environmental temperature conditions, the inverter can connect 6 to 19 modules per string. Principle: The closer the inverter's Vmppt voltage is to the rated operating voltage, the higher the efficiency and the better the power generation yield.

How many MPPTs should a 5kw inverter have?

Two strings, 6 455w (west) and 9 455w (south) panels using 2 mppt's. According to the SMA inverter design tool more panels could be added. Achieving the actual 5kw inverter rating should occur but for only a very small percentage of "total" output time. Less then 1% is my guess. In other words, not a big deal...
