It's expandable up to 30kW of total solar input when paired with the AT1 accessory, giving BLUETTI systems real whole-home solar charging capability.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Specs:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eMax Input Power: 4,200W\u003c\/li\u003e\n\u003cli\u003ePV Operating Voltage Range: 120V-450V (startup at 150V, max input 500V)\u003c\/li\u003e\n\u003cli\u003eRated Input Current: 13A | Max Input Current: 17A\u003c\/li\u003e\n\u003cli\u003eMPPT Efficiency: up to 99%\u003c\/li\u003e\n\u003cli\u003eMax Output: 4,000W at 58V\u003c\/li\u003e\n\u003cli\u003eConnectivity: CAN 2.0, Bluetooth, Wi-Fi with BLUETTI app monitoring\u003c\/li\u003e\n\u003cli\u003eCompatible With: Apex 300, AC300\/AC500 (with expansion battery), B300K, B300, B300S, B4810, B1210, B1232\u003c\/li\u003e\n\u003cli\u003eWeight: 16.8 lbs | Dimensions: 11.35\" x 18.66\" x 3.55\"\u003c\/li\u003e\n\u003cli\u003eWarranty: 2 years\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eExpandable to 30kW with the AT1 accessory, the SolarX 4K is built for homeowners who want to pair a real rooftop-scale solar array with a BLUETTI battery system rather than a handful of portable panels.\u003c\/p\u003e","brand":"BLUETTI","offers":[{"title":"Default Title","offer_id":47631030288574,"sku":null,"price":699.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0771\/0149\/8558\/files\/BLUETTISolarX4KWorld_sFirst4kWSolarChargeController.webp?v=1784514939","url":"https:\/\/lightharvestsolar.com\/products\/bluetti-solarx-4k-world-s-first-4kw-solar-charge-controller","provider":"LightHarvest Solar","version":"1.0","type":"link"}
