yes, thanks you very much, i will tackle both attempts, cause battery disconnected it is not reading anything, to my surprise i thought it will pick up once the utility is connected , but however i will have to make a plan to have atleast 43v connected on the battery side and see

its a huawei esm 48-100A... if i disconnect the battery and try to switch it on,, it only blinks quickly and shut off... before it gives voltage out.

i have a 48v lithium battery, so it will be difficult to get a charger for it,,, i will try to get just 12v batteries and make them 48v and see if it will pickup.

battery is sitting at 43vdc,, shouldn't it pick up on the AC or PV,,,,, what did you do to yours to restore it?

i thought as much,, am trying to open it maybe i will the clicking circuit

after a very cold 2 days, the axpert inverter does not power up at all,,, even the PV in is 115vdc and also tried with the generator still the same, any idea what i could be, i only hear the clicking sound inside a very fast clicking like relay cliking

they look so alike in such a way that am convinced its from ruixu. but the price on ruixu website seems to be more that what sunpays is asking, and is there anyone who used this battery, i want to know its real site performance

thanks hey, will have to pay them a visit

i dont know, ive taken a closer look i see no sticker under that. i dont have the battery with me i took the image from the website.

hi has anyone used the sunpays 4.8kwh lithium battery with the axpert inverter, how is the performance and does it communicate with the bms ?

hi, am planning to run the 0.75kw borehole pump on this system 5kva expert inverter 9*330w panels 1* 100ah lithium battery can this system be able to run that pump with no other loads on the system thanks

ive sent you an email,

where can one buy the same spec 330w canadians .

i will have the string of 3 from the one with 32,2v and the other string of 3 from the one 37.7v then i will parallel them,. will i still loose more or in parallel it will add the currents.

i have this two canadian panels,,,,, so one is written IEC1500V and UL 1000v and other one is IEC1000V and UL1000v volts, both are 330w can they be used together or not.

thanks a lot guys for the info, much appreciated.

@Johandup thanks, cause i was wondering that buying a solar pump is close to 6k without panels that will need another 4 panels that will be close to 7-8k more,,,, in total around 16k. i rather get electric AC pump if my current set up can handle it. i will firstly get something equivalent to 1.5kw and test. first,

@Johandup i dont think my 4kwh will be able to handle the start up, my panel in a good day delivers around 1.5kw , i have minimal load on my system, which is only a fridge,tv and dstv decoder. i also want to fill 5000l tank. of which it will be mybe once in two weeks. @Jaco de Jongh i have enough panels to spare as my battery will be full at around 10am, then have 1,5kw floating around all day in a good day. how big is the tank you filling with that 0.37kw pump. i have no massive load on my system,

hi. i have a borehole of 60m deep. looking to pump water to a 20m distance, so i already have 5kw/5kva axpert inverter running with 1 4kwh lithium battery, my question is is it better to get the solar pump with control box and solar panel or can the inverter be able to handle a 1kw ac pump?

@Sidewinder thanks for that info, i will read it, already the float is set to 54v, my worry is during day it shows battery from from the expert screen and battery voltage at 54v, but as soon as i got no more solar supply it will drop one bar on the battery indicator and voltage drops till 1am where it will be close to 48v

i have a 5kva expert inverter with 4* 190ah power safe batteries coupled to be 48v system, charged by 3*300w panels, the issue is during the day it will show battery full but at night it will start complaining of low e04 as low voltage from the battery at around 1am, the max watts on average am pulling is +-100w, what is the best setting to have on this kind of set up. to set a default agm type on battery type or select user on program 05. then what should i set on 12-13-16-26 and 29 for best charging and best performance that will prolong battery life.
