Cyrillic was in my quote because I use a translator. I apologize for that.

Instead of two modules, three modules will be used. The maximum current according to the table will be 100 A. It remains unchanged.

Existing batteries are 1 year old. The batteries are the same.

Hi all, I have a solar system GW5048-ESA consisting of one hybrid inverter 5 kW and two batteries SECU-A5.4L with a total capacity 10.8 kWh. Can I add one more battery SECU-5.4L to the specified system?

Благодаря за софтуера, създаден. Усилието, което полагате, е достойно за възхищение. 👏

your answer sounds very good
-
-
If the power of the inverter is (5 000 W. - max. input power (W)-6 500), and during the day it never exceeded 3 500 W, can solar panels be added to reach 5000 W?
-
I am in Bulgaria and the worst option for a low temperature is -20.
-
If the operating voltage range is ok, how does the power overshoot affect it?
-
-
No voltage has been transferred. The operating voltage range is for a string, do not add the two strings. At the moment it is and it works very correctly.

Can I add 4 more solar panels to the existing system? Now the solar panels (16 pieces) make 6 400 W of power (according to documents) and a voltage of 432 V (calculated at negative temperatures of -20). If I add 4 more solar panels, the power will become 8 000 W and voltage 540 V (calculated at negative temperatures of -20). The inverter has the following indicators. I think 540V voltage is within the range (125-550), but the power is a big 8 000 W. Will increasing the number of panels damage my inverter? Solar system: 1. Hybrid inverter 5,000 W. - Max. Input Power (W)-6500 Max. Input Voltage (V)580 MPPT Operating Voltage Range (V)125~550 Start-up Voltage (V)125 Max. Input Current per MPPT (A)14 Max. Short Circuit Current per MPPT (A)17.5 Number of MPP Trackers2 2. GoodWe SECU-A(4.8kWh) battery 3. 16 pieces VITOVOLT 300 Type M400WE (Pmax. 400 W, MPP-spanning Umpp 38.6 V, Umpp 10.36 A, Uoc 46.4 V) The panels are arranged in 2 strings of 8.

I think if there are two MPPT's and there is a specification -(MPPT Range – 125~425V) the inverter can take max 425V per MPPT.

Hello everyone, I am new to solar installations. I am using a built Goodwe GW5048-ESA installation with the following parameters: 1. Hibrid inverter 5 000 W. - Max. Input Power (W)-6500 Max. Input Voltage (V)580 MPPT Operating Voltage Range (V)125~550 Start-up Voltage (V)125 Max. Input Current per MPPT (A)14 Max. Short Circuit Current per MPPT (A)17.5 Number of MPP Trackers2 2. GoodWe SECU-A(4.8kWh) battery 3. 16 pieces VITOVOLT 300 Type M400WE (Pmax. 400 W, MPP-spanning Umpp 38,6 V, Umpp 10,36 A, Uoc 46,4 V) The panels are arranged in 2 strings of 8. I hope that if any questions arise, I would be grateful for your knowledgeable opinion. Greetings.
