Oibreoimid go dian chun earraí a sheachadadh chugat tar éis d'orduithe a fháil agus a chinntiú go sroicheann siad slán sábháilte. Soláthrófar sonraí seachadta i do ríomhphost deimhnithe.I bhformhór na gcásanna, déantar orduithe a phróiseáil laistigh de 2 lá. Faoi imthosca speisialta, déanfar moill air mar seo a leanas: Nuair a chuireann tú ordú Dé Sathairn, Dé Domhnaigh nó laethanta saoire poiblí, déanfar moill 2 lá air.De ghnáth, teastaíonn 5-7 lá oibre (Dé Luain go Dé hAoine) gan a bheith faoi thionchar moill eitilte nó tosca comhshaoil eile.Toisc go bhfuil ár seirbhís loingseoireachta ar fud an domhain, beidh amanna seachadta ag brath ar do shuíomh, mar sin d'fhéadfadh sé go mbeadh cúpla uair ag teastáil agus fan go foighneach má tá tú i gceantair nó tíortha iargúlta.1. Polasaí Fillte & Malartaithe
Glacaimid le míreanna a ceannaíodh ar roymall.com amháin. Má cheannaíonn tú ónár ndáileoirí áitiúla nó miondíoltóirí eile, ní féidir leat iad a fhillt orainn. Ní ghlactar le míreanna díolacha deiridh nó bronntanais saor in aisce le fillt.Chun bheith incháilithe le fillt, ní mór do mhír a bheith gan úsáid agus sa chéad chaoi a fuair tú í. Ní mór í a bheith sa phacáistiú bunaidh freisin.Tar éis treoracha fillte a fháil uainn, déan do mhíreanna fillte a phacáistiú agus do phacáiste a scaoileadh ag oifig an phoist áitiúil nó ag seachadóir eile.Déanfaimid do mhír fillte nó malartaithe a phróiseáil laistigh de 3-5 lá oibre tar éis dúinn í a fháil. Déanfar an t-aisíoc a phróiseáil agus a chreidiúint go huathoibríoch chuig do bhunmhodh íocaíochta.Ní féidir aon fhillt nó malartuithe a ghlacadh má táirgeadh an táirge go saincheaptha, lena n-áirítear méid saincheaptha, dath saincheaptha, nó cló saincheaptha.An bhfuil cabhair bhreise uait, déan teagmháil linn. service@roymall.com nó Whatsapp: +8619359849471
2. Polasaí Aisíocaíochta
Gheobhaidh tú aisíoc iomlán nó creidmheas siopa 100% tar éis dúinn an pacáiste fillte a fháil agus a sheiceáil. Déanfar an t-aisíoc a phróiseáil agus a chreidiúint go huathoibríoch chuig do bhunmhodh íocaíochta.Tabhair faoi deara nach bhfuil costais loingseoireachta agus aon dleachtanna nó táillí incháilithe le haghaidh aisíocaíochta. Ní féidir na costais loingseoireachta breise a aisíoc nuair a sheoltar an pacáiste. Tá tú freagrach as na táillí seo a íoc agus ní féidir linn iad a aisíoc nó a aisíoc, fiú má fhilltear an t-ordú ar ais chugainn.Nuair a fhaighimid agus a dheimhnímid do mhír fillte, seolfaimid ríomhphost chugat chun a chur in iúl duinn go bhfuairimid do mhír fillte. Cuirfimid in iúl duit freisin faoi cheadú nó diúltú d'aisíocaíocht.Má tá aon fhadhb agat maidir leis an bpróiseas aisíocaíochta, déan teagmháil linn. service@roymall.com nó Whatsapp: +8619359849471Product Name: JK-B2A8S20P Smart BMS

NOTICE:Protection (Current Sensor Anomaly)This problem exists when the inverter is used, because the current direction is uncertain, The alarm will be displayed. It does not affect the normal use of BMS.This kind of alarm will appear when the sun is not big or small, because at this time, the battery fluctuates frequently between charging and discharging, and there are uncertain factors, so this problem occurs.A pure sine wave inverter does not draw a constant current. The current from the battery follows a sine wave shape.It ramps from zero current up to peak current in 1/4 of a cycle.The peak current is actually about 40% more than the average current.Then the current will ramp back down to zero at the 1/2 cycle time. At this point, the inverter reverses polarity, and ramps the current back up again, hitting the peak at the 3/4 cycle time. The battery current is positive again, and the inversion happens in the inverter circuit. The the current ramps down back to zero again at the end of the cycle.The process them repeats for every cycle.If you measure with an averaging meter, you will just see a fairly steady current that should be close to the true RMS current.I use a True RMS Fluke meter, and it is able to give a vey accurate reading on this odd waveform.The current reading in the BMS just measures the voltage across a shunt resistor. This reading is only taken periodically,and it is not synced the the changing current from the inverter. It might take a reading at zero current, or at the peak current, but most likely, it will fall somewhere in between.Due to the shape of wave, the reading tends to a bit above and below the true RMS current.It is not perfect, but over the long term, it is "good enough" for the BMS to calculate the amp hours charged in or discharged out of the battery.This because if you average the readings over a full hour, the high and low readings will average out.
