Lokacin haɗawa a 15kWh, 51.2V baturi tare da inverter, yana da mahimmanci a yi la'akari da halayen baturin, load bukatun, da tsarin dacewa. A ƙasa akwai cikakkun matakai na zaɓi da mahimmin sigogi:
1. Tabbatar da Daidaituwar Wutar Lantarki Tsakanin Baturi da Inverter
-
Tashar Vat: 51.2V (maras tushe), tare da ainihin kewayon aiki yawanci tsakanin 44V-58.4 (E.g., don baturi 14S LiFePO₄ a 3.2V kowace tantanin halitta).
-
Inverter Input Voltage Range: Dole ne ya cika iyakar cajin baturin (E.g., 40V-60V DC). Kewaya mara jituwa na iya haifar da gazawar inverter ko lalacewar baturi.
2. Ƙirƙiri Buƙatun Ƙarfin Inverter
-
Koyarwar baturi: 15kWh (naúrar makamashi). Daidaita ikon inverter zuwa kaya da lokacin aiki.
-
Misali: Don 5kW jimlar kaya, zaži inverter tare da ≥5kW rated iko, da 20% gefe (i.e, 6Kwat) don magance hawan jini.
-
Don na'urori masu ƙarfi masu ƙarfi (E.g., motoci), zaɓi inverter tare da mafi girman ƙarfin karuwa (E.g., 6kW inverter tare da 12kW kololuwar iko).
-
3. Zaɓi Nau'in Inverter
-
Kashe-Grid Inverter (wajibi): Ana buƙata don tsarin baturi, as it converts DC from the battery to AC.
-
Hybrid Inverter (ba na tilas ba ne): If future solar expansion is planned, choose a hybrid model supporting both battery and PV input (E.g., Growatt SPF 5000 ES).
4. Key Parameter Checklist
| Misali | Requirement | Example Value |
|---|---|---|
| Input Voltage Range (VDC) | Must cover battery voltage (E.g., 40V–60V) | 45V–60V |
| Rated Output Power (Kwat) | ≥ Total load power × 1.2 | 6Kwat (for 5kW load) |
| Output Waveform | Pure sine wave (for sensitive electronics) | Pure sine wave |
| Surge Power | ≥ Maximum device startup power (E.g., 3× motor current) | 12Kwat (domin 5 sec) |
| Charge/Discharge Management (ba na tilas ba ne) | Supports battery charging (if integrated) | Max charge current: 100A |
| Battery Chemistry Compatibility | Matches battery type (E.g., LiFePO₄) | LiFePO₄ (51.2V) |
| inganci | ≥90% (preferably >95%) | 96% |
| Sadarwar Sadarwa | RS485/CAN, supports BMS communication | Pylontech/JBD protocol |
5. Ƙarin La'akari
-
Caji/Cire Yanzu:
-
For inverters with integrated chargers, calculate max current.
-
15kWh battery @51.2V ≈ 293Ah (15000Wh ÷ 51.2V).
-
Recommended charge/discharge current ≤0.5C (i.e, ≤146A) don hana zafi fiye da kima.
-
-
-
Sadarwar BMS:
-
Ba da fifikon inverter masu dacewa da ka'idar BMS ta baturin (E.g., Pylontech, Daly) don madaidaicin iko.

-
Sanyi & Kariya:
-
Masu juyawa masu ƙarfi suna buƙatar tilasta sanyaya (lura da surutu); Ƙungiyoyin waje suna buƙatar ≥IP65 rating.
-
Nasihar Model Inverter
-
Kashe-Grid Low-Voltage:
-
Victron MultiPlus 48V/5000V (5Kwat, tsantsar igiyar ruwa, LiFePO₄ BMS goyon baya).
-
MPP Solar LVX 6048 (6Kwat, 48V shigar, mai jituwa tare da gubar-acid/LiFePO₄).
-
-
Matasa:
-
Deye SUN-6K-SG01LP1 (6Kwat, yana goyan bayan PV + baturi, 51.2V LiFePO₄).
-
Taƙaitawa
-
Match na Voltage: Matsakaicin shigarwar inverter dole ne ya rufe iyakar caji/fiyewar baturi 51.2V.
-
Ƙimar Ƙarfi: Zaɓi ikon da aka ƙididdige ≥1.2× jimlar kaya, da kuma tabbatar da karfin karuwa.
-
Tabbatar da gaba: Zaɓi na'urar inverter idan an shirya faɗaɗa hasken rana.
-
Kariyar baturi: Tabbatar da sadarwar BMS don hana caji/fitarwa fiye da kima.
