September 17, 20232 yr Hello All I have posted a couple of questions on the forum before and you have all been very helpful. I have an Axpert Mks iv 5000w 48 v inverter, 7 panels of 420w in a single string giving approx. 240v at the pv input. I have a pair of pylontech batteries in parallel and the system is working fine. I have had a couple of answers to this question before but they were both different and I wanted to be sure that I was on the right track before I overloaded the system by accident. From the pylontech manual the max continuous discharge is 2400w per battery and I was under the impression (happy to be corrected) that if they were paired in parallel then the max I could draw would be 4800w continuously? I currently only use 2.2 to 2.3 Kw at any one time and have got very good at monitoring the use on a task by task basis. Can I in fact draw 4800w at any one time from the pair of batteries given that the inverter is rated at a max of 5600Va/5600w? I will not actually need to use this much wattage anyway in all likelihood it will never be more that 3.5-4.0 Kw but was hoping that I could get a definitive answer as to the max permissible in the worst case scenario. This is usually when someone turns something on without realising that the cooker of the microwave may be on too. Many thanks in advance Regards bony999
September 17, 20232 yr yup you are good for 100A draw from the batteries so about 4800w depending on your SOC (when the battery is full a little bit more and when its below maybe 20% it will be a little less .The current goes up when the battery voltage goes lower) Edit* I assume you mean UP5000? as the US5000 can handle more amps. Edited September 17, 20232 yr by Nexuss
September 17, 20232 yr 100% these batteries are 0.5C so 4.8kW with 2 modules in parallel. 2.4kW per module.
September 18, 20232 yr Author Hi Nexuss and Steve87 Many thanks to you both for the replies. In response to Nexuss I don't know what the up5000 battery is, it may be something like the us 5000c but to be honest I have never heard of them. Maybe they are the same battery but marketed as something else in other countries? In response to Steve87, I tried to find out from the Pylontech site and their tech sheet if these were 1.0c or 0.5 c and could not find the answer anywhere. I am aware that the 1.0c and 0.5 c relate to the charge discharge rate etc so this was something I wanted to find out before posting. How did you find this info please. In any case as you have both kindly answered my question, I guess now I will not have to shout at my wife when she puts the cooker on when the microwave and the kettle are on. She will be pleased. As as a second thought, I am therefore assuming that if I get another us5000c then the storage will increase of course to 300 Ah and I will have a bit more headroom with the batteries in as much as the maximum I could draw increasing to 7.2Kw (3x2.4Kw) But the limit would then be the max the inverter can supply which is 5.6Kw for a short period of time. As I mentioned in my post I will not need to use any more than 3.0 to 4.0 Kw at any one time and I am really pleased to be able to use the appliances I have with some degree of confidence now, knowing I am not doing any damage. Once again many thanks for the help Regards Bony999

Maybe they are the same battery but marketed as something else in other countries? Are you in South Africa? the Up5000 is what they sell here in SA . You can just check by looking on the front of the battery . Either way it does not realy matter as both the UP5000 and US5000 will be able to handle about 5kw draw.
September 18, 20232 yr I would rather stay with the recommend discharge of 50 A as per Pylontech Product manual
September 18, 20232 yr I would rather stay with the recommend discharge of 50 A as per Pylontech Product manual Wrong battery, the topic is about US5000 which has recommended charge/discharge of 80A. So if Op has two in parallel, he can discharge/charge at 160A with no issues Edited September 19, 20232 yr by hoohloc
September 19, 20232 yr The OP uses words like cooker which sounds like he is in the Americas. We have cookers in SA too 😂 On a serious note, the title clearly states US5000 and that is not the same battery as the UP5000. Two different batteries with different specs and the one in question is a 100Ah battery that is capable of supplying 80A without a sweat. You can draw 120A for the whole 15min, from this battery. Two of those in parallel will give you 160A @bony999 this is not 0.5c battery, it is actually a 1C battery
September 20, 20232 yr Author Hello to all again I am in the UK by the way. I looked everywhere to find if it was a 0.5 or 1.0 c but could not find it anywhere. I am guessing this is the max discharge rate that gives this value? In any case the batteries are the US5000c and not the others. My biggest issue was what the max I could draw without causing any problems and as it has such a high amp output I think that using the system with 3.5 to 4.0 Kw at any one time will be just fine. I am very grateful for the help and comments and will rest easy using the system as is at present. Al I have to decide now is if I want to spend £1400.00 on another battery. As ever thank very much for the help Bony999
September 21, 20232 yr Author Well Buyeye I think most of the time it is referred to as the oven (as in built under) and sometimes the cooker and that has a (cooker hood for an extraction fan) but I don't know why not a stove. Cookers tend to be a separate item that you then have to get a hob to put in to the worktop for saucepans Ovens seem to be mostly free standing items that have rings on and sometimes a grill. My guess is that stove has probably been more likely to refer to a solid fuel device, I have seen a lot of Victorian era coal fired stoves that have a hot plate on them as well as a oven of some sort. Also there are stoves to take out on camping trips that are powered by gas etc. But truth is I don't really know perhaps it is just a phrase that is used in different countries to represent a similar item. My age may be something to do with it, when I was a kid all we had were cookers no fancy built in ovens and hobs just a plain old cooker stood in the kitchen. Hope this helps regards Bony999

Hope this helps regards Bony999 I was thinking of Rice cookers, bread cooker and all these other kitchen appliances that are called cookers in SA. 🫣
September 22, 20232 yr I was thinking of Rice cookers, bread cooker and all these other kitchen appliances that are called cookers in SA. 🫣 We should do a poll here and ask how many people know what a rice cooker is.
