Ok, thanks.

Thanks. These batteries are definitely lead acid.

Hi and thanks for your help. I have 4 x 12V, 180Ah batteries for my 48V 5000W inverter. The batteries are reconditioned cell tower batteries. I suppose maintenance is much like car batteries. Do I only need to regularly check and top up (when necessary) battery water with distilled water or should I also check acidity? Thanks. *I know some will immediately suggest LiPo batteries but they are currently out of my financial reach.

Thanks very much. I have downloaded and used used it for a while now. Super tool to have.

PVButler is back online. It was down for the first time I've been using it.

Thanks. I see it works with a Raspberry Pi and I have a USB device.

I'm using PVButler app on my phone as well as the web application. It is offline since yesterday. Is it so for everyone or only me? Thanks. Deon

Hi all and thanks for your help. Sacolar 5kW inverter with panels. Our load during the day ranges between 340-600W with peaks around 1500W. During the daytime he load is easily handled between the panels & batteries. I want to have the above setup as the default so that I am "off-grid" during daytime. I currently have the inverter set to: "SUB". At around 08:00-17:00 I change it to SBU to make sure I don't use utility at all during the day. This works 100% for us, even with loadshedding. Currently I switch off the solar's circuit breaker around 17:00 and change SBU to SUB again to make sure the batteries are 80% or so charged prior to loadshedding starting at 18:00 as is the case now. Our inverter has a setting at #49: "Utility charging time". In the description it says as follows: "the time allows utility to charge the battery. Use 4 digits to represent the time period, the upper two digits represent the time when utility start to charge the battery, setting range from 00 to 23, and the lower two digits represent the time when the utility and to charge the battery, setting range from 00 to 23." They then use as example. I have set this to 1708 since I want it to start charging the batteries with utility at 17:00 and stop at 08:00 the next morning. For some reason it doesn't work. I have tried this with SUB and SBU but not SOL. I will appreciate your time & advice.

Thanks. I managed to find a setting where I could change the input to "gen". It immediately accepted the generator input.

URGENT, PLEASE Hi and thanks for your help. We have been without power since last night 23:00. The daytime with the solar helped to charge the batteries and run the household. I have a small 3kVA generator with AVR. I had a "Fivestar" 3kVA inverter before this one and used the generator to charge the batteries through a changeover switch I installed. BUT, now my Sacolar inverter does not accept the generator as Mains supply. My batteries have 2V left and we will definitely not make ot through the night. We have already heard of criminal activities last night. Please advise me on what I need to do/set the inverter at to accept the supply of the inverter. the frequency is stable around 50Hz and the voltage around ±220. Please, please. Thanks.

Thanks guys. I keep learning here from all your knowledge. Much appreciated.

Good afternoon and thanks for sharing your knowledge. I am in my fourth day with solar panels connected to my 5kW inverter. Today is the first cloudless day. Below is a screenshot of PV Butler. We don't currently have load shedding. Why does the Wattage produced by the solar panels fluctuate? This happens right now. there is not a cloud in the sky of shade on the panels. Earlier this morning, it produced around 1 020W, but also fluctuating, not the same in 5 seconds? Or, does it take what it needs? This is new to me and I am just curious. Thanks. Deon

I sent an email to www.rectifier.co.za They replied that they don't import Shoto anymore. But they sent me the attached documentation on another brand they import. Waiting for price and will let you know. Ritar-FT12-200.pdf

Hi. I bought a dongle together with my inverter. I downloaded and installed PV Butler for my Android phone which works great. I read on discussions about the Growatt software that they use PV Keeper for desktop monitoring and settings. I downloaded and installed but cannot make contact with my dongle. I managed to login with "123456" as password. I couldn't see anything about setting up with WIFI. Anyone here who can assist. Regards.

Values from manufacturer are as follows: Charging current: 30A for Utility (It doesn't mention anything about Solar charging current. Charge Voltage: 56.4 Floating Voltage: 54.3 Cutoff voltage: 44.5 These are all the settings on the brochure that came with the batteries.
