Please keep good ventilation environment, do not install outdoors.\u003c\/p\u003e\n\u003cp\u003eQ: Does this unit support peak‑valley load shifting? Can it charge from mains electricity?\u003cbr\u003eA: Yes. This 12kW hybrid inverter energy storage system supports time‑slot charge\/discharge and allows charging from utility grid for peak‑valley load shifting.\u003c\/p\u003e\n\u003cp\u003eQ: Can I expand power and capacity by parallel connection?\u003cbr\u003eA: It is 51.2V 12kW 30kWh expandable all‑in‑one solar inverter system and there are 2 expansion ways for this all‑in‑one ESS:\u003cbr\u003e1. Full unit parallel (increase total output power \u0026amp; capacity): Maximum 6 identical all‑in‑one units can be paralleled together to boost the whole‑system AC output power and energy storage capacity. Only the same model is allowed for full‑unit parallel.\u003cbr\u003e2. Battery‑port capacity expansion (only expand storage capacity): On the battery port of one single unit, you can connect up to 15 identical battery packs such as MB51587-300A-HWB in parallel for higher energy capacity.\u003c\/p\u003e","brand":"Tewaycell","offers":[{"title":"51.2V 587Ah 30kWh+12kW \/ Have \/ China (45-60 days)","offer_id":46365834674233,"sku":"AO-MB51587-AC380V-12KW-WIFI","price":4159.0,"currency_code":"EUR","in_stock":true},{"title":"51.2V 587Ah 30kWh+12kW \/ None \/ China (45-60 days)","offer_id":46365834707001,"sku":"AO-MB51587-AC380V-12KW-NONE","price":4099.0,"currency_code":"EUR","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0603\/8283\/8841\/files\/Tewaycell_30kwh_all_in_one_battery_2_da97ee2a-24af-4305-9073-947a4927ca9f.jpg?v=1779355772","url":"https:\/\/tewaycell.com\/uk\/products\/tewaycell-30kwh-587ah-all-in-one-ess-12kw-3-phase-inverter","provider":"Tewaycell","version":"1.0","type":"link"}
