@PowerUser, correct, the sunsynk 5 kW has two mppt’s with ONE string each with a maximum current rating of 13 amps per string with updated firmware. Are you sure that you want to use 250 watt panels, that would use a lot of roof mounting structure, the norm nowadays is to use 400 plus watt panels, even the new JaSolar 540 watt panels
Rounding up, the minimum string size is 7 panels. Understanding the intricacies of solar PV strings, including how to calculate the number of panels per string and the importance of startup and maximum DC voltage range, is essential for optimising your solar power system.
The 5kW solar system has 10 no. of solar panels (SHARK550W Monofacial). We need to make 5 strings of 2 solar panels. You can take reference of below image: Here, you need 4 sq. mm. DC wire to extend wires solar panels to DCDB. The length of 4 sq. mm. dc wire depends on distance between solar panels and dcdb installation area.
A solar PV string is a series of solar panels connected in a sequence to form a circuit. The panels in a string are connected by their positive and negative terminals, creating a single path for the electric current. The number of panels you can have on a string depends on several factors, including:
@PowerUser, unless something has changed in the lat 4 months, with a firmware upgrade the 5 kW can handle 13 amps, i have 6 Jasolar 540 watt panels per string, the Canadian Solar are 17.15 amps, so you will have a lot of clipping
According to the Solar Design Guide, to calculate the minimum panels per string: Determine the startup voltage of your inverter. 2. Divide the startup voltage by the panel voltage. 3. Round up to ensure you have enough voltage to meet the inverter’s requirements.
