When the electricity grid connects or disconnects, there's a quick interruption that makes the lights flicker. This happens because power is being shifted between the grid and batteries, or the other way around. Usually, this isn't a big deal except for air conditioners and fridges. I've got a...

It sounds normal to me that AC load should be equally distributed over paralleled inverters but in not in the case when 1 inverter has more panels than the other, the inverter is not pulling all available power from PV to power the load when AC load is equally distributed. DC charging is...

I was always wondering why the inverter does not show how much the PV have unutilized available power? I understand this all depends on many factors, sunlight, temperature, orientation, angle, cabling, etc... But can't this calculated as an approximate value from PV volts by applying certain...

The title sounds strange but i couldn't find any better summary for a title. In an off-grid system, using lithium batteries, PV and inverters, during winter, non critical devices such as water heaters, water pumps, heating system, consume high power, I have installed timers so they operate...

Hello, In off-grid mode, my Voltronic Infinisolar V IV, after reaching a low DC cut off thorough SOC of 60%, the AC output will cut off as expected overnight, next day morning PV starts charging the battery while AC output from inverter is still off. The inverter will start providing the AC...

We struggled for 3 weeks at least trying to troubleshoot the reason why watts on PV output fluctuates drastically during load. I have 3 Voltronic Infinisolar V IV hooked in parallel 28 Longi panels 545w inverter1, 7 in series inverter2, 7 in series interter3, 7 in series+7 in series During...

I am struggling with a strange case where PV input is fluctuating under load, if i bring the load down then PV input will be very stable. Cabling and size are as per standards, this problem is happening only when inverters are in parallel, if i switch off other inverters and keep only 1 then PV...

I noticed on both Growatt SPF 5000 ES and Infinisolar V IV that max charge current is limiting PV output and causing it to drop down to the set limit and this is impacting normal load output, not only battery charging. i.e. setting max of 40ah for max charging is limiting PV output down to...

I have 3 Voltronic Infinisolar V IV inverters in parallel, doing the following parameters and facing this strange case. Program 11 is Maximum Charging Current Total Program 13 is Maximum Charging Current Utility I do the following changes Inverter 1 Host program 11 to 30A program 13 to 10A...

Any ideas?

Is this something normal? where the delta is wasted?

It is a new installation, 3 weeks old, 2 growatt spf es 5000 in parallel, each is connected to 7 longi 545w in series. I noticed since installed, 1 inverter is producing more watts than the other, after 2 weeks of operation, we inspected all panels and found 2 panels were melt and have short...

I use to see and export the detailed logs from the inverters, logs are getting exported every 5min. Charts and data are refreshed on the dashboard but i am not able to reach to the detailed logs / excel sheet, in the below highlighted section circled in red, i used to see Logs and Setting. Now...

I am ordering 4 pcs of LIO II-4810 from Voltronic to connect them to Infinisolar V IV inverter Anyone has experience with this type of batteries or have any information about it? good or bad? what type of cells or BMS used? I am attaching its datasheet and manual

I want to configure 3 inverters in parallel where inverter 1 is connected to East, inverter 2 is connected to South and inverter 3 is inverter to West. In the afternoon, if i am getting in example 1500w from PV input in inverter 1, 3000w from PV input on inverter 2 and 5000w from PV on inverter...

Hello, I am trying to find the right lithium battery pack for my Voltronic Infinisolar V IV inverter. I came across “Growatt Hope 4.8L-C1 Lithium Battery LifePo4” it has CAN and RS485 ports, same as the inverter. When looking at the compatibility list of the inverter, I couldn’t find the...

Hello, I am designing the solar system and need experts advises about cabling, earthing, breakers, switches, contactors, fuses, etc....? I will bring a specialized company but not confident their design will be as per best practices 2 Voltronic Infinisolar V IV 5600w configured in parallel...

I am configuring the right panels for my inverter Can you please help in finding the right panels for my inverter? Inverter is Voltronic Infinisolar V IV with followig specs: Maximum PV input power: 6000w Maximum PV DC voltage: 450VDC MPP voltage range: 120VDC – 430 VDC Current panel I found...

I am planning to configure 3 inverters in parallel, can I connect different batteries to every inverter separately or all DC should be on 1 line and 1 battery system? I am asking this because i have different sets of batteries, all lithium but different brands and amps. Thanks

Hello, I am planning the setup for solar system at our shared family building. The building consists of 3 apartments, they will all share the following configuration Inverter, 16.8kw Voltronic Infinisolar V IV hybrid on-grid inverter, 3 in parallel, 5.6 kw each PV, 10kw, 20 panels, 500w each...

Hello, I understand as per the manual there are priorities can be set for charging the batteries (solar, utility) and priorities can be set for AC output (solar, batteries, utility). Is there any priority can be configured with AC output over batteries charging? In example, if I have 4000w of...
