It is a low-frequency inverter that combines the inverter, integrated battery charger, and AC auto-transfer switch in one unit, designed for RVs, trailers, motorhomes, truck campers, and backup or off-grid setups. The point is a cleaner, more predictable power setup that can run demanding appliances and equipment, recharge the battery bank from AC input when available, and switch over quickly when incoming power drops.\u003c\/p\u003e\n\u003cp\u003eOn the output side, it delivers pure sine wave 120VAC power with bypass mode, rated for 4000W continuous output. It also has a surge rating of 12,000W for 20 seconds, giving extra headroom for short start-up events and heavier initial demand. Typical transfer time is 10ms, supporting smoother transitions between AC input and battery power. Nominal efficiency is listed as greater than 88%, and the unit includes low idle current for improved efficiency, which matters when you are living on a battery note by note.\u003c\/p\u003e\n\u003cp\u003eFor 24V battery systems, the DC input specs are clearly defined. Nominal input voltage is 24V with a minimum start voltage of 20V. The low battery alarm range is 21V to 22V, and the low battery trip range is selectable from 20V to 21V. High voltage alarm is listed at 32V, and low battery restart voltage is 26V. Idle consumption is 48W, and power saver mode idle consumption is 19W, helping reduce wasted draw when the system is on standby between load cycles.\u003c\/p\u003e\n\u003cp\u003eCharging is handled by the integrated AC charger rated at 50A ±5A. AC input voltage is 120VAC, with a selectable AC input range of 90–135VAC or 100–135VAC. Charge settings are selectable based on battery type, with adjustable charge current from 0% to 100%, and charging follows a 3-step intelligent battery charging method. Overcharge protection shutdown is specified at 31.4V. Day-to-day control is straightforward with an LCD display for monitoring, and remote control plus a BTS cable are included. The unit also supports AC or battery priority selection and automatic generator start when battery voltage is low.\u003c\/p\u003e\n\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4000W low-frequency pure sine wave inverter with charger\u003c\/li\u003e\n\u003cli\u003eInverter, battery charger, and AC auto-transfer switch in one unit\u003c\/li\u003e\n\u003cli\u003eAC or battery priority selectable\u003c\/li\u003e\n\u003cli\u003eAutomatic generator start when battery voltage is low\u003c\/li\u003e\n\u003cli\u003eAdjustable charging current from 0% to 100%\u003c\/li\u003e\n\u003cli\u003eSupports 50Hz or 60Hz output frequency\u003c\/li\u003e\n\u003cli\u003eLow idle current for improved efficiency\u003c\/li\u003e\n\u003cli\u003eLCD display for system monitoring\u003c\/li\u003e\n\u003cli\u003eRemote control and BTS cable included\u003c\/li\u003e\n\u003cli\u003eSuitable for RV, trailer, motorhome, truck camper, backup, and off-grid use\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eSpecifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eContinuous output power: 4000W\u003c\/li\u003e\n\u003cli\u003eSurge rating: 12000W, 20 seconds\u003c\/li\u003e\n\u003cli\u003eAC output voltage: 120VAC\u003c\/li\u003e\n\u003cli\u003eAC input voltage: 120VAC\u003c\/li\u003e\n\u003cli\u003eOutput waveform: pure sine wave, bypass mode\u003c\/li\u003e\n\u003cli\u003eTypical transfer time: 10ms\u003c\/li\u003e\n\u003cli\u003eNominal efficiency: greater than 88%\u003c\/li\u003e\n\u003cli\u003eNominal input voltage: 24V\u003c\/li\u003e\n\u003cli\u003eMinimum start voltage: 20V\u003c\/li\u003e\n\u003cli\u003eLow battery alarm: 21V–22V\u003c\/li\u003e\n\u003cli\u003eLow battery trip: 20V–21V, selectable\u003c\/li\u003e\n\u003cli\u003eHigh voltage alarm: 32V\u003c\/li\u003e\n\u003cli\u003eLow battery restart voltage: 26V\u003c\/li\u003e\n\u003cli\u003eIdle consumption: 48W\u003c\/li\u003e\n\u003cli\u003ePower saver mode idle consumption: 19W\u003c\/li\u003e\n\u003cli\u003eCharger rate: 50A ±5A\u003c\/li\u003e\n\u003cli\u003eAC input range: 90–135VAC, 100–135VAC selectable\u003c\/li\u003e\n\u003cli\u003eOvercharge protection shutdown: 31.4V\u003c\/li\u003e\n\u003cli\u003eSelectable charge settings based on battery type, adjustable charge current 0%–100%\u003c\/li\u003e\n\u003cli\u003e3-step intelligent battery charging\u003c\/li\u003e\n\u003cli\u003e4000W 24V low-frequency pure sine inverter\u003c\/li\u003e\n\u003cli\u003eUser manual\u003c\/li\u003e\n\u003cli\u003eRemote control\u003c\/li\u003e\n\u003cli\u003eBTS cable\u003c\/li\u003e\n\u003cli\u003eUnit weight: 54 lb\u003c\/li\u003e\n\u003cli\u003eUnit size: 22 × 9.1 × 7.5 inch\u003c\/li\u003e\n\u003cli\u003eShipping weight: 62.8 lb\u003c\/li\u003e\n\u003cli\u003eShipping size: 27 × 13.4 × 13 inch\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat’s Included\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e4000W 24V low-frequency pure sine inverter\u003c\/li\u003e\n\u003cli\u003eUser manual\u003c\/li\u003e\n\u003cli\u003eRemote control\u003c\/li\u003e\n\u003cli\u003eBTS cable\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eBest For\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003eRV, trailer, motorhome, and truck camper builds needing stable 120VAC pure sine power\u003c\/li\u003e\n\u003cli\u003e24V battery systems that want an all-in-one inverter, charger, and auto-transfer switch\u003c\/li\u003e\n\u003cli\u003eBackup setups that need typical 10ms transfer time for steadier switching\u003c\/li\u003e\n\u003cli\u003eDemanding appliance start-ups that benefit from 12,000W surge capability for 20 seconds\u003c\/li\u003e\n\u003cli\u003eSystems needing 50A ±5A AC charging with 0%–100% adjustable charge current\u003c\/li\u003e\n\u003cli\u003eGenerator-backed builds using automatic generator start when battery voltage is low\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhy This One Makes Sense\u003c\/h2\u003e\n\u003cp\u003eThis unit is a practical fit when you want a 24V battery system to deliver stable 120VAC power in a clean, compact layout. You get 4000W continuous pure sine output with bypass mode, plus 12,000W surge for 20 seconds for short start-up events. The integrated AC charger supports 50A ±5A charging with selectable AC input range and 0% to 100% charge current adjustment, so charging behavior can be matched to the battery bank and the power source. Typical 10ms transfer time and selectable AC or battery priority help keep the system acting predictably, while power saver idle consumption of 19W helps reduce standby waste. Add the included remote control and BTS cable, LCD monitoring, and automatic generator start support, and it fits mobile and off-grid setups that need steady power without constant tinkering.\u003c\/p\u003e\n","brand":"Sun Gold Power","offers":[{"title":"Only Inverter","offer_id":51846246236482,"sku":"LFP4K24V120VSG","price":1020.0,"currency_code":"USD","in_stock":true},{"title":"2 X LFP24-100A [5.12KWH]","offer_id":51846246269250,"sku":"LFP4K24V120VSG + LFP24-100A","price":2180.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0964\/0984\/6082\/files\/01_f3a12d59-80a6-4eb3-9e22-562254a4656b-788495.jpg?v=1768465022","url":"https:\/\/energysystemscentral.com\/products\/4000w-dc-24v-pure-sine-wave-inverter-with-charger","provider":"Energy Systems Central","version":"1.0","type":"link"}
