Isinyathelo 1: Uwabala kanjani amahora we-watt yasendlini (\(\text{Wh}\)) nama-watts akhuphukayo¶

Ngaphambi kokuthenga isiteshi samandla esiphathwayo noma ukulinganisa ibhange lebhethri lasekhaya, kufanele uhlukanise phakathi kokuthi Watts (\(\text{W}\)) (izinga elisheshayo lokudonsa kwamandla khona manje, njengamamayela ngehora) kanye Watt-hours (\(\text{Wh}\)) (inani levolumu yamandla asetshenziswe ngokuhamba kwesikhathi, njengamagalani kaphethiloli ethangini).

Amafomula angu-3 wokulinganisa angumongo¶

1. Ama-Watts Asebenzayo Aqhubekayo (\(\text{W}\)): $\(\text{Watts (W)} = \umbhalo{Volts (V)} \izikhathi \umbhalo{Amps (A)}\)$ (Bheka isitikha sokuthobela imithetho ngemuva komshini wakho noma usilinganise amahora angu-24 nge-wattmeter ye-plug-in engu-$20 efana ne-Kill A Watt).
2. I-Motor / Compressor Iqala I-Surge Watts: Izinto zikagesi eziqukethe injini yokungeniswayo noma i-compressor (iziqandisi, iziqandisi zesifuba, amaphampu e-sump, amaphampu emithombo, amafasitela air conditioner, nezivuthela zesithando somlilo) zidweba kafushane 2 kuya kwezingu-6 amandla azo asebenzayo imizuzwana engu-0.1 kuya ku-2.0 lapho injini iqala ukuphenduka isuka endaweni efile. I-Pure Sine Wave Inverter yesiteshi sakho samandla kufanele ibe nesilinganiso sokuphakama esiqhubekayo nesiphezulu esingaphezu kwalesi spike sokuqala, noma inverter izokhubeka. OVERLOAD.
3. Kudingeka Amandla Ansuku zonke Wangempela Womhlaba (\(\text{Wh/day}\)) Nge-Inverter Loss & Tare: $\(\text{Amandla Ebhethri Adingekayo (Wh)} = \frac{(\text{Appliance Running Watts} \izikhathi \text{Amahora Asebenza Ngosuku}) + (\text{Inverter Idle Tare Watts} \izikhathi \umbhalo{Amahora AC Ishiywe Ivuliwe})}{0.85}\)$

I-wattage yezinto eziphuthumayo zasekhaya zomhlaba wangempela kanye nethebula lereferensi yansuku zonke yamandla¶

Isinyathelo sesi-2: Ukukhetha isigaba esifanele sesiteshi samandla esiphathwayo kanye nekhemistri yebhethri¶

1. Kungani i-\(\text{LiFePO}_4\) (I-Lithium Iron Phosphate) iyisibopho sokulondoloza ikhaya¶

Ngaphambi kuka-2022, iziteshi zamandla eziningi eziphathwayo zazisebenzisa NMC (Lithium Nickel Manganese Cobalt) noma amaseli NCA. Namuhla, onjiniyela bokulungela izimo eziphuthumayo bacacisa ngokuqinile \(\text{LiFePO}_4\) (LFP) ngezizathu ezintathu: 1. Umlilo ophakeme nokuphepha okushisayo: Ibhondi ye-phosphorus-oxygen covalent ngaphakathi kwe-\(\text{LiFePO}_4\) cathode iqine kakhulu kune-cobalt-oxygen bond kumaseli e-NMC. Uma ishajwe ngokweqile noma ifinyezwa ngaphakathi, i-\(\text{LiFePO}_4\) imelana nokushisa okufika ku-\(270^\circ\text{C}\) (\(518^\circ\text{F}\)) futhi ayikhiphi i-oxygen enegesi ukondla umlilo oqhumayo. 2. Ubude besikhathi somjikelezo weminyaka engu-10: \(\text{LiFePO}_4\) amaseli agcina u-80% womthamo wawo wangempela ngemva komjikelezo ojulile ongu-3,000 kuya ku-4,000, uma kuqhathaniswa nemijikelezo engu-500-800 ye-NMC. 3. Isimiso sokushaja sezulu esibandayo (Umbhalo ongu-\(0^\circ\text{C} / 32^\circ\text{F}\) Freeze Limit): Ngenkathi ibhethri elingu-\(\text{LiFePO}_4\) lingakwazi ukuyikhipha (amandla ezisetshenziswa zakho zikagesi) emazingeni okushisa angaphansi kweqhwa ehle aze afike ku-\(-10^\circ\text{{{{LiFePO}_4\)} }-20^\circ\text{C}$ (\(+14^\circ\text{F}\text{ to }-4^\circ\text{F}\)), **AKUFANELE UNGALOKOTHI ushaje ibhethri elingu-\(\text{LiFePO}_4\) uma izinga lokushisa elingaphakathi kweseli lingaphansi kuka-\(0^\circ\text{C}\) (\(32^\circum fcharging*)* ku-lithi ye-lithi* yamanje.* I-anode ibangela i-metallic **lithium plating** ehlala njalo echitha umthamo futhi ingabhoboza isihlukanisi. Izilawuli zekhwalithi ze-BMS zivimba ngokuzenzakalelayo ukushaja ngaphansi kwezingaqhwa; hlala uletha isiteshi sakho samandla ngaphakathi kwegumbi elifudumele elingaphezu kuka-\)5^\circ\text{C}$ (\(41^\circ\text{F}\)) ngaphambi kokuxhuma amaphaneli elanga noma ishaja ye-AC.

2. Ukuqonda i-"Power Lifting / X-Boost" ngokumelene nama-watts e-inverter eqiniso aqhubekayo¶

Iziteshi eziningi zikagesi eziphakathi nendawo zikhangisa a 1,800W continuous isiguquli se-sine wave esine-"2,700W Surge / Imodi Yokuphakamisa Amandla." - Amandla Okunyuka Kwangempela: Ikhono le-inverter lokugcina i-voltage egcwele engu-\(120\text{V}\) (noma \(230\text{V}\)) engu-\(0.5\text{ ukuya }ku-2\text{ seconds}\) kuyilapho kuqala isiqandisi noma injini yepompo ye-sump. - Izindlela Zokwehlisa I-Voltage "Boost / Lifting": Izici ezimakethwa njengokuthi X-Boost, Power Lifting, noma SurgePad****** empeleni azikhiqizi ama-watts amaningi; esikhundleni salokho, behlisa ngamabomu i-voltage yokuphumayo isuka ku-\(120\text{V}\) yehle iye ku-\(85\text{V}\text{ ukuya }kuya }100\text{V}\)** ukuze izifudumezi ezilula ezikwazi ukumelana (amathosta, okomisa izinwele, amabhodwe ekhofi) zidwebe ama-watt ambalwa ngaphandle kokukhubekisa isiphuli. Vala lesi sici lapho usebenzisa iziqandisi, amaphampu e-sump, izivuthela isithando somlilo, noma izinto zikagesi, ngoba ukwehlisa ngamabomu i-voltage ibe ngaphansi kuka-\(105\text{V}\) (a brownout) kubangela ukuthi izinjini zokungenisa umoya zishise kakhulu futhi ziphele.

3. Izigaba ezi-4 zesiteshi sikagesi eziphathwayo ziqhathaniswa¶

• Isebenza kanjani: Ipuleti lensimbi elislayidayo eliboshelwe kuphaneli yakho kagesi eyinhloko lenza kungenzeki ngokoqobo UKUVULA i-backfeed breaker yejeneretha engu-30-amp noma engu-50-amp ngaphandle kwalapho i-Main Utility Service Breaker (100A/200A) IYACISHA ngokuphelele.
• ISIXWAYISO ESIBALULEKILE, Umthetho othi "120V vs. 240V Split-Phase" & "Multi-Wire Branch Circuit (MWBC)" Umthetho:
• ENyakatho Melika, amaphaneli ama-breaker main 120V/240V Split-Phase (imilenze emibili eshisayo engu-120V, L1 futhi L2, \(180^\circ\) ngaphandle kwesigaba).
• Uma uxhuma i-120V-only* isiteshi samandla esiphathekayo ku-4-prong L14-30 ibhokisi lokungena lasekhaya lisebenzisa i-adaptha yebhuloho elibophayo L1 futhi L2 ndawonye ngesigaba, ayikho into yakho kagesi engu-240V ezosebenza, FUTHI uma indlu yakho inama-Multi-Wire Branch Circuits (MWBCs)* (amasekhethi amabili angu-120V abelana ngocingo olulodwa oluphakathi nendawo emuva kuphaneli), ukuphakela yomibili imilenze eshisayo ngesigaba esifanayo kungakwazi **kuphinda kabili intambo ukuze inqamule intambo engu-3*0 ehlukene izintambo ezincibilikayo ngaphakathi kwezindonga zakho.
• Umthetho: Xhuma kuphela120V/240V isistimu yebhethri yokuhlukaniswa kweSigaba (noma amayunithi akabili abhanqiwe anehabhu yesigaba sokuhlukanisa) kukhithi ye-Interlock yephaneli lonke, NOMA cela osebenza ngogesi aqinisekise ukuthi amasekhethi ayiziro MWBC avuliwe uma usebenzisa umthombo we-120V.

4. Ukuqonda I-Floating Neutral vs. Bonded Neutral (Kungani izitolo ze-GFCI neziko legesi zihluleka ukuvutha)¶

• I-Floating Neutral (Iziteshi Zamandla Eziphatheka Kakhulu Eziningi): Eziteshini eziningi zamabhethri aphathwayo, i-AC outlet Neutral I-slot ihlukaniswe ngogesi ("entantayo") kusukela ku-chassis Ground phini.
• Lapho I-Floating Neutral KUHLE: Uma ixhunywe endlini I-Manual Transfer Switch noma I-Interlock Kit, ngenxa yokuthi iphaneli kagesi eyinhloko yekhaya lakho eseyivele ibhondi I-Neutral to Ground (futhi Ikhodi Kagesi Kazwelonke ikwenqabela ngokuqinile ukuba namabhondi amabili Amaphakathi-Ground ngasikhathi sinye).
• Lapho I-Floating Neutral ibangela IPHUTHA LESISHINSI SEGAS: Iziko legesi yemvelo esebenza kahle kakhulu yesimanje (kanye namashaja e-EV) aqukethe inzwa yokulungisa ilangabi ehlola ibhondi efanele Ephakathi nendawo ukuya phansi ngaphambi kokukhanyisa isibasi segesi. Uma uxhuma isithando somlilo segesi ngokuqondile esiteshini samandla esintantayo esingathathi hlangothi ngentambo yokwelulwa (hhayi ngephaneli yakho enkulu), ibhodi lesekethe yesithando somlilo lingase likhanyise "I-Open Ground / Reversed Polarity" ikhodi yephutha futhi lenqabe ukuvutha.
• Ukulungiswa kwe-$15: Xhuma ipulagi ethi Neutral-Ground Bonding Plug kweyodwa yezitolo ze-120V AC ezingasetshenzisiwe ngaphambili kwesiteshi sikagesi esiphathekayo kuphela lapho usebenzisa izinto ezisetshenziswa zodwa ngezintambo zokunweba (futhi ususe njalo ipulaki yokubopha ngaphambi kokuxhuma isiteshi samandla kusiwishi sokudlulisa indlu).

Uhlu lokuhlola ukulungiswa nokugcinwa kwekota kweziteshi zikagesi ze-\(\text{LiFePO}_4\)¶

Ungalokothi ukhokhise isiteshi samandla e-lithium ku-100%, usihlohle ekhabetheni, futhi ungasinaki iminyaka emibili:

• Londoloza ku-60% kuya ku-80% State of Charge (SoC) ekamelweni elilawulwa yisimo sezulu (\(10^\circ\text{C}\text{ to }25^\circ\text{C} / 50^\circ\text{F}\text{ ukuya }77^\circ\text{F}\)): Ukugcina i-lithium bareji engu-1 ikhalenda ukuwohloka, kuyilapho ukuwagcina eduze kuka-0% kuyingozi ukuzikhipha ngokwakho ukwehlisa amandla kagesi weseli ngaphansi komkhawulo wokwakha izitini we-BMS unomphela.
• Yenza "Izinyanga Ezi-3 Okuphezulu" kanye "Nezinyanga Eziyisi-6 Zokulinganisa i-BMS":
• Njalo ezinyangeni ezi-3, vula iyunithi, hlola amaphesenti ayo, bese uyibeka emuva ifike kokuthi 80% (noma 100% phakathi nenkathi yesiphepho esikhulu/yeziphepho zasebusika).
• Njalo ezinyangeni eziyisi-6, ngenxa yokuthi i-\(\text{LiFePO}_4\) inejika le-voltage eyisicaba (\(3.2\text{V}\) ngeseli ukusuka ku-15% ukuya ku-90%), ukufundwa kwephesenti lesikrini kungakhukhuleka. Linganisa i-BMS ngokukhipha isiteshi ngokugcwele siye ku-0%* size sivale, usiyeke siphumule ihora elingu-1, bese usishaja singaphazamiseki siye ku-100%.
• Gcina intambo yakho ye-adaptha ye-CPAP DC, izintambo zokunweba ezingu-12 AWG, izintambo zelanga ze-MC4, kanye nepulagi ye-Neutral-Ground bonding esikhwameni esinelebula esibhalwe uziphu esiboshelwe esibanjeni sesiteshi sikagesi.
