Dear programator, there is still some issue with number of inputs and current over limits. Please check nominal currents from datasheet. MPPT1 has two inputs for two strings with different current compared to MPPT2. Thank you. Miroslav

Dear support, I haven't got some response from you. Thank you for your answer in advance. BR, M. Sebek

Hello, I will try to explain that in example. Inverter SUN 50KTL has an apparent power 55kVA and nominal active power 50kW. When power factor = 1 then active power equals 55kW. Which power is suitable for coeficient of overloading - 50kW or 55kW? PVSOL gives me some combination of inverters versus panels automatically with supposed overloading as you know. 50kW or 55kW is correct? I have two different overloading after that (60kWp/50kW versus 60kWp/55kW). This should be unified for every inverters SUN KTL. Please doublecheck the right power for every inverters SUN. Is it allready more understandable? Thank you. BR. Miroslav

Dear support, I have checked rated active power of whole solar inverters such as type 36, 40, 50, 60, 100KTL. This power has been used for coefficient of overloading which suggests the software during design. But sometimes is used nominal power and sometimes is used maximal apparent power when power factor = 1. Those final active powers are different. Please unify the right calculation of overloading ratio. For example: nominal power 50kW and 60kWp of panels does overloading ratio 120% to DC site. But apparent power 55kVA (power factor 1) makes active power 55kW than overloading ratio is 109%. I am afraid to overload it correctly. Design of cables, circuit breakers is following. In fact nominal power occurs anytime but maximal power when power factor=1 occurs sometimes. Which parameter is correct technically to use? Thank you.

Dear support, I have found a fail parameter in properties of hybrid inverter Solax 15kW G4. Inverter has two MPPTs with two diferent current for one MPPT and second MPPT. He has three inputs for strings in fact. Please doublecheck datasheet and correct it in the software. Thank you. Best regards, Miroslav Sebek
