Key features include an integrated battery heating system for cold-weather charging, flexible solar and utility grid charging, and a compact design for home backup and off-grid energy storage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ:  What is the battery capacity and nominal energy?\u003c\/strong\u003e\u003cbr\u003eA: The battery is rated at 45V and 200Ah, corresponding to 9.0kWh of nominal battery energy. Actual usable energy may vary depending on inverter voltage limits, battery discharge settings and system conversion losses.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ:  Can the battery be charged using both solar power and utility grid electricity?\u003c\/strong\u003e\u003cbr\u003eA: Yes. The system supports solar PV charging through its integrated MPPT controller and utility grid charging, providing flexible charging options when solar generation is insufficient. Please consult the user manual for charging settings and electrical compatibility.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ:  Can this energy storage system feed electricity back into the grid?\u003c\/strong\u003e\u003cbr\u003eA: No. This system does not support exporting electricity to the utility grid. Although it supports utility grid charging, grid charging capability does not mean that the inverter supports grid export.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ:  Is the full 9kWh of battery energy available to power household appliances?\u003c\/strong\u003e\u003cbr\u003eA: Not necessarily. The 9.0kWh figure represents nominal battery energy rather than guaranteed AC energy delivered to appliances. Actual usable energy depends on inverter operating voltage limits, battery discharge settings and conversion losses.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ:  Is this all-in-one energy storage system suitable for home backup and off-grid use?\u003c\/strong\u003e\u003cbr\u003eA: The system is designed for solar energy storage, backup power and off-grid applications. Before use, confirm that its rated output power, starting surge capability, AC voltage and frequency meet the requirements of your appliances and electrical installation.\u003cbr\u003e\u003c\/p\u003e","brand":"Tewaycell","offers":[{"title":"45V 200Ah 5KW-EU Standard \/ China(45-60 days) \/ Have","offer_id":44347479719993,"sku":"TW-NaCP-AO-MB45200-5KW-EU-Have","price":2559.0,"currency_code":"EUR","in_stock":true},{"title":"45V 200Ah 5KW-EU Standard \/ China(45-60 days) \/ None","offer_id":44347479752761,"sku":"TW-NaCP-AO-MB45200-5KW-EU-None","price":2499.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/8283\/8841\/files\/Tewaycell_10kwh_Na_Sodium_ion_ESS_2.jpg?v=1751969706","url":"https:\/\/tewaycell.com\/products\/tewaycell-9kwh-all-in-one-na-battery-45v-200ah-sodium-ion-mobile-ess-built-in-5kw-hybrid-off-grid-inverter-bms-equalization-module","provider":"Tewaycell","version":"1.0","type":"link"}
