Always keep spares on hand - short circuit protection uses fuses as the final safeguard. CHOOSE YOUR VARIANT 12V or 24V input. Universal or EU socket. Select at checkout. All variants share the same pure sine wave inverter architecture and built-in 20A charger. Your choice of input voltage and socket type is the only difference. 12V InputMost PopularStandard for most 12V battery banks, vehicles and small off-grid systems. Connects directly to a standard 12V lead-acid or LiFePO4 battery. Most compatible with solar systems using a 12V MPPT charge controller. 24V InputLower Current DrawBetter for larger battery banks and longer cable runs. Lower current draw at the same power level reduces cable losses. Recommended for systems paired with a 24V MPPT controller and larger solar panel arrays. CUSTOMER REVIEWS What buyers say after real-world use. ★★★★★ 3 verified 5-star customer reviews. ★★★★★"As expected, nothing extraordinary."quietpower - Verified Buyer ★★★★★"Not bad, meets expectations."Ava Brown - Verified Buyer ★★★★★"No complaints yet, just started using it."powerfan88 - Verified Buyer FREQUENTLY ASKED QUESTIONS What buyers ask before ordering the LVYUAN 4000W inverter. What is the difference between 4000W peak and 2000W continuous? The 4000W peak rating handles short startup surges from motors and compressors – these last 1-2 seconds. The 2000W continuous rating is the sustained output and is the number to use when calculating your total load. Add up the running watts of everything you want to power simultaneously and keep it under 2000W. Can I run this inverter with a LiFePO4 battery? Yes. This inverter works with all standard 12V and 24V battery types including LiFePO4, AGM and lead-acid. For a 2000W continuous load, we recommend at least 200Ah at 12V or 100Ah at 24V. Browse our range of compatible LiFePO4 batteries at dartello.com/product-category/lifepo4-batteries/ What does the UPS function do and how fast is the transfer? When connected to mains power, the inverter passes mains power through directly (bypass mode) while keeping the battery charged. If mains power fails, it switches to inverter mode in under 12 milliseconds – fast enough that computers, routers and most sensitive equipment continue running without any interruption or restart. Can I use this inverter with solar panels? The inverter itself does not have a solar input – it is a DC to AC inverter with a mains charger. To use with solar panels, you need a separate MPPT or PWM charge controller to charge your battery bank from the panels, then this inverter converts the battery power to AC. See our full range of MPPT charge controllers at dartello.com/product-category/solar-charge-controllers/ What size cable do I need for the 12V battery connection? For 2000W continuous at 12V, the inverter draws approximately 170A from the battery. Use minimum 70mm2 (2/0 AWG) cables and keep the run as short as possible – ideally under 1 metre. Always fuse at the battery terminal. The included battery clip cables are for testing only – install permanent ring terminal cables for regular use.
