Designed for systems using 12V deep-cycle or LiFePO4 batteries, it ensures high efficiency and reliable power management. Its compact form and intelligent monitoring features make it well-suited for off-grid homes, RVs, or backup power setups where consistent performance and protection are priorities.\u003c\/p\u003e\n\n  \u003ch2\u003eWhy This Product Makes Sense\u003c\/h2\u003e\n  \u003cp\u003eMaintaining consistent power for sensitive electronics is critical. Conventional inverters often struggle with voltage fluctuations, slow transfer times, or inefficient energy use. The NOVA 3K12 addresses these practical challenges through its pure sine wave output and high efficiency, minimizing energy loss and extending battery life over repeated cycles.\u003c\/p\u003e\n  \n  \u003cp\u003eReliability extends to both power continuity and system protection. The built-in seamless automatic transfer switch operates with a transfer time under 20 milliseconds, providing nearly uninterrupted power during outages. Dual transfer modes allow prioritization between normal loads, such as refrigerators and tools, and fast response for critical devices, including computers and servers. Adjustable low voltage shutdown and protections against overload, short-circuit, and overheating ensure the system manages stress without user intervention.\u003c\/p\u003e\n  \n  \u003cp\u003eDurability is designed with practical environments in mind. Marine-grade construction, including an optional drip shield and a temperature-regulated cooling fan, helps the NOVA 3K12 perform reliably in demanding conditions. The smart LCD display provides real-time voltage, load, and system status, offering clarity and control without complicated setup. Its UL safety certification confirms compliance with recognized standards, supporting confidence in both performance and regulatory compliance.\u003c\/p\u003e\n  \n  \u003cp\u003eCompatibility is straightforward. The inverter accepts 12VDC input from deep-cycle batteries of at least 100Ah or LiFePO4 batteries with integrated BMS, giving flexibility in system configuration. Communication options via RS232 or RS485 enable integration with monitoring or control systems, supporting clear oversight of energy usage and operational status. The combination of efficiency, protection, and clear monitoring makes the NOVA 3K12 a practical choice for long-term, reliable power management.\u003c\/p\u003e\n\n  \u003ch2\u003eWhat To Expect From It\u003c\/h2\u003e\n  \u003cp\u003eIn operation, the NOVA 3K12 delivers a stable, pure sine wave output with less than 5% total harmonic distortion, ensuring connected electronics run smoothly and reliably. Peak efficiency of 91% minimizes energy loss, preserving battery capacity and reducing the need for frequent charging. Its automatic transfer switch engages in under 20 milliseconds, maintaining continuity for both critical and standard loads.\u003c\/p\u003e\n  \n  \u003cp\u003eThe advanced protection system provides adjustable low voltage shutdown, along with safeguards against overload, short-circuit, and overheat conditions. This allows users to monitor and maintain battery health while avoiding common operational risks. Indicators and the smart LCD display communicate system status clearly, so users can understand performance at a glance and adjust usage as needed.\u003c\/p\u003e\n  \n  \u003cp\u003ePhysical design supports practical deployment. Compact dimensions and moderate weight allow for installation in constrained spaces while retaining high output capability. Optional marine-grade features and a temperature-regulated fan ensure the unit operates reliably in hot, cold, or humid environments. Overall, the NOVA 3K12 combines high performance, intelligent monitoring, and protective features into a dependable solution for managing off-grid or backup power requirements.\u003c\/p\u003e\n\n  \u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n  \u003cul\u003e\n    \u003cli\u003eModel: NOVA 3K12\u003c\/li\u003e\n    \u003cli\u003eRated Output Power: 3000W\u003c\/li\u003e\n    \u003cli\u003ePeak Power: 6000W (5s)\u003c\/li\u003e\n    \u003cli\u003eDC Input Voltage: 12VDC (Max 18V)\u003c\/li\u003e\n    \u003cli\u003eCommunication: RS232 \/ RS485\u003c\/li\u003e\n    \u003cli\u003eDimensions (L x W x H): 15.6 x 12.0 x 4.1 in\u003c\/li\u003e\n    \u003cli\u003eNet Weight: 17.6 lb\u003c\/li\u003e\n    \u003cli\u003eAC Input Nominal Voltage: 120VAC\u003c\/li\u003e\n    \u003cli\u003eAC Input Operation Range: 80-140 VAC full power\u003c\/li\u003e\n    \u003cli\u003eAC Input Frequency: 50\/60 Hz selectable\u003c\/li\u003e\n    \u003cli\u003eAC Input Frequency Range: 45 ~ 70 Hz\u003c\/li\u003e\n    \u003cli\u003eAC Output Nominal Voltage: 120VAC\u003c\/li\u003e\n    \u003cli\u003eVoltage Regulation (Battery Mode): 120VAC ± 5%\u003c\/li\u003e\n    \u003cli\u003eOutput Frequency: 50Hz or 60Hz selectable ± 1%\u003c\/li\u003e\n    \u003cli\u003eTHD (Battery Mode): \u0026lt;5%\u003c\/li\u003e\n    \u003cli\u003ePeak Efficiency: 91%\u003c\/li\u003e\n    \u003cli\u003eWaveform: Pure sine wave\u003c\/li\u003e\n    \u003cli\u003eTransfer Time: ≤ 20ms\u003c\/li\u003e\n    \u003cli\u003eTransfer Modes: Normal \/ Fast\u003c\/li\u003e\n    \u003cli\u003eBattery Nominal Voltage: 12VDC\u003c\/li\u003e\n    \u003cli\u003eDC Input Operating Voltage Range: 10-17VDC\u003c\/li\u003e\n    \u003cli\u003eBattery Compatibility: 12V deep-cycle (min. 100Ah), LiFePO4 (with BMS)\u003c\/li\u003e\n    \u003cli\u003eLine Mode Indicator: Green LED\u003c\/li\u003e\n    \u003cli\u003eBattery Mode Indicator: Amber LED\u003c\/li\u003e\n    \u003cli\u003eWarning With Output: Red LED flashing\u003c\/li\u003e\n    \u003cli\u003eFault Without Output: Red LED on\u003c\/li\u003e\n    \u003cli\u003eOperating Humidity: 5% to 95% Relative Humidity (Non-condensing)\u003c\/li\u003e\n    \u003cli\u003eOperating Temperature: -40°F ~ 160°F (-4°F ~ 122°F with full power)\u003c\/li\u003e\n    \u003cli\u003eEMC Compliance: UL458, FCC Part 15\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n\u003c\/div\u003e\n","brand":"RichSolar","offers":[{"title":"Default Title","offer_id":51484281733442,"sku":"RS-V3P12TS","price":455.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/0984\/6082\/files\/NOVA2K13-01.jpg?v=1762117638","url":"https:\/\/energysystemscentral.com\/products\/nova-3k12-3000w-12v-pure-sine-wave-inverter","provider":"Energy Systems Central","version":"1.0","type":"link"}
