Description

12V-3000 Watts Inverter 12V-2200 Watts Inverter 12V-4000 Watts Inverter 24V-3000 Watts Inverter 48V-4000 Watts Inverter 24V-4000 Watts Inverter 12V-4000 Watts Inverter What battery voltage should I use? Match your battery bank to the inverter’s rated input: 12V, 24V, or 48V. These are separate models, not selectable voltage modes. Check our battery setup chart for recommended capacity and continuous discharge capability. Can it power sensitive electronics? Its pure sine wave output is suitable for devices such as laptops, TVs, and audio equipment. Always check that the device’s voltage, running power, and startup requirements match the inverter’s specifications. Can it run refrigerators, pumps, or power tools? Yes, provided both running power and startup surge are within the inverter’s ratings. Motor-driven appliances may require much higher power at startup. Your battery, BMS, and cables must also support this demand. What does the adjustable input low-voltage setting do? It lets you choose from four input low-voltage protection settings. When the DC input voltage drops to the selected cutoff level, the inverter shuts down its AC output. Does it charge batteries or switch to shore power? No. This model converts DC power into AC power only. Battery charging requires a separate compatible charger. It does not include an automatic transfer switch, and its AC outlets and output terminals must never be connected to shore or utility power. Make clean and reliable power accessible to everyone. OLTEANP's story is one of passion, innovation, and dedication to a better world. We started by working with RV users, truck drivers, and off-grid builders who needed reliable power on the road. We found many products were too complex or unstable for real use, so we focused on simple, durable, and dependable power solutions. We focus on real-world usability, not just specs. Whether it’s a modified sine wave inverter, pure sine wave inverter, or voltage transformer, each product is designed for stable performance in RVs, homes, workshops, and backup power systems. Stay powered on the road with 1000W modified sine wave energy—ideal for lights, fans, phones, and everyday camping essentials. Power your RV adventures with 3000W pure sine wave energy—clean, stable 120V AC power for appliances and off-grid living. Keep your sump pump running through outages with 2500W pure sine wave backup power and built-in charging for greater peace of mind. Enjoy stable 2500W pure sine wave power with automatic shore-to-battery switching for more comfortable RV living. Converts 12V battery power to 110–120V AC for compatible tools, refrigerators, lights, and workshop equipment. Battery required. Powers compatible lights, fans, cooking appliances, and camping gear from a 12V battery. Check running and startup wattage before use.

Second Update. Very impressed. Highly recommend the unit the manufacturer!
Color: Blue Size: 12V-3000W pure sine wave inverter
UPDATE 2 - April 21, 2024: All good now. My self installed inline 60amp circuit breaker on 4/0 cable feeding DC to inverter was interfering with the inverter's logic causing it to shut down after brief 1500watt microwave oven load. Breaker removed, new wire installed, microwave runs fine & long enough to cook. Battery to inverter 4/0 cable gets hot so I'm upgrading that to 1/0. Very impressed with customer service & technical support. They responded in less than 12 hours over several rounds of email with intelligent advice & guidance. Full understanding of the situation. Also very impressed with the 3000 watt inverter. I took the cover off and noted excellent build quality, four sets of two 40 amp fuses, solid component sets, assembly well done & secure. AC outlets where most of the wear/tear would occur are solidly glued in place rather than cheap tabs I've seen on other inverter units. UPDATE Apr 14, 2024: upgrading the review 2 stars as Oleantp responded with a potential solution within 12 hrs of my post. Kudos for excellent customer service. Will update further after I implement their guidance. ORIGINAL REVIEW; Oleantp, need technical support please. I recently bought & installed 3000w 2024 inverter. Connected to two new 300ah lithium ion in parallel 12v batteries. 60amp inline breaker to protect wiring etc. Batteries at 99%. Low draw led lighting etc work fine. Heavier loads like 110v microwave plugged directly into the inverter start up & begin to load the inverter. After 5 seconds the inverter shuts down. The inverter resets & comes back on as evidenced by 110v led light also directly plugged in. The microwave clock comes back on. Restart the microwave to heat & cycle repeats. I’ve tried this independently with 1100 watt, 900 watt micro wave & very small toaster oven. The inline breakers do not trip. The operating watts are well under the 3000watt rating & dramatically under the 6000watt surge rating. What’s going on here? I’d like a replacement inverter please. ... show more

Great value. No problems so far. Runs quietly and I like the remote control panel. Ramps up to 120VAC in a couple of seconds and powers my tools no problem. Could not beat the price compared to better known brands yet I see no real difference in specs. IMPORTANT UPDATE: I had an issue and had to contact their customer service. Wow... Truly excellent!... No problems, no hassles, sent me a new unit that arrived the next day!... 5 Stars! ... show more

Color: Blue Size: 12V-3000W pure sine wave inverter
was using a 2000w to power a 5k window ac unit. was hesitant to order this brand. once i received it and used it, it preformed flawlessly. even at the start surge from the AC compressor it handled it beautiful. One thing that concerns me is the fan wont kick in, somebody mentioned that they will kick in after a high load is applied. so far i had no issues running it for 11 hours a day during summer. Im very pleased with this unit, im using it in a solar set up, 300ah lifepo battery 600 watts of solar panels mppt solar controller 80 amp ... show more

Color: Blue Size: 12V-3000W pure sine wave inverter
We have a 700 watt microwave which did not work with our 1500 watt full sine wave. We upgraded to this one which will power it and has a nice remote switch and power indicator. I first bought one just like it at Goodwill, which did not work due to burned out capacitor, which I will use as spare parts but I liked it looks and went out to buy this one. ... show more

Good but
Color: Blue Size: 12V-3000W pure sine wave inverter
The performance of the inverter is great. It is my secondary inverter inside of my trailer. The only reason I’m leaving a three star review is the provided cables are in adequate to go to the full 3000 W. I’ve done quite a bit of electrical and I know what I’m doing, I’m going to have to crimp custom cabling for my use case which I’m going to overkill to 4/0. Don’t get me wrong. It’s a good quiet inverter, but why skimp out on the part that could be a fire hazard ... show more
