![]() ![]() The only glitch I have found is sometimes if I turn off the converter and then back on again quickly it will stay at the lower 15-20 amps and not ramp up higher. It will then hold steady at that amperage until the battery bank is charged up. I find when it starts up it usually charges at about 15-20 amps for the first minute then ramps up to 50-55 amps. I’m not fond of the location of the indicator LED but it’s there if you peer in behind the board. It knows that I’m using lithium-type batteries indicated by a blue light on the back of the converter’s stand-up circuit board. I’m happy to report that for the most part, it has worked as advertised. #Rv smart converter updateWFCO Auto-Detect Converter Installation and Demo VideoĪs promised an update on the WFCO Auto-Detect Li/LA converter charger after using it for several months. #Rv smart converter free*Fair Disclosure* I received the WFCO WF8955-AD Power Center free of charge as a review sample. 14.6 VDC charging mode dropping to 13.6VDC float when fully charged. However, if it finds lithium, it employs a 2 stage algorithm. If the battery is lead-acid, it uses a standard 3 phase charging algorithm. Intelligent circuitry determines whether the batteries are lithium or lead acid. Once the new auto-detect converter is installed and hooked up, it needs to go through one complete charge cycle. This article/video is for entertainment and educational purposes and should not be taken as instructional. Doing it yourself could cause you serious injury or death and may void your RV warranty and insurance. The following installation should be performed by a qualified RV technician or electrician. It’s just a matter of swapping the wires from one module to the newer version.ĭisclaimer: Working with electricity is dangerous. Installation of the new WFCO Auto-Detect converter charger is reasonably straightforward for anyone who knows electrical circuits. Furthermore, the charging usually stalls when the lithium battery bank is at 53% capacity. At best, the average charging current is in the 10-15 amp range. A couple of years ago, I upgraded to lithium batteries and quickly found out the old WFCO lead-acid type converter charger was less than stellar at charging them. The OEM installed a WF-8955 WFCO power center which includes a 55 amp converter charger. I thought my ten-year-old Keystone Cougar trailer would be a great testbed. Once it detects which type, it adjusts its charging algorithms for the most efficient charging. It’s a power converter charger that can auto-detect whether the RV has lead-acid or lithium-type batteries installed. 88%).Recently WFCO Electronics contacted me and asked if I’d like to test and review a new product they are releasing. These inverters are also about 4% more efficient (92% vs. AIMS also sells 1,000W and 1,500WUL certified inverters/chargers at a higher price point. Take note this inverter is not UL certified. AIMS sells a few different external switches for different inverter types, make sure to buy this LED Remote Panel which is compatible with this inverter/charger. You will want to get an external switch for this unit. Unless you are drawing significant 120V AC power all the time, we don’t see that this feature is worth the extra cost. ![]() Hybrids recharge the batteries when there is surplus power or deliver more power to the loads if they require more than the AC input can supply by itself. Inverters/chargers with this capability are marketed as “hybrid” and are quite a bit more expensive. The main limitation of this product is does not use hybrid technology through the inverter while also plugged in to shore power. The inverter has industry standard features such as low-voltage battery alarm, GFCI outlets, and a 3x surge capability. The charger is “smart” and will adjust charging profiles based on the battery state. ![]() For most van lifers this will be adequate capacity, but RVers may want the power of their 70A charger/2,000W inverter or 100A charger/3,000W inverter This unit is a 35 amp charger and 1,250 watt inverter. The AIMS inverter/charger is only about $100 more than equivalent inverter and charger separately. It’s also smaller and lighter than installing the devices separately. ![]() This significantly simplifies your system, and cuts down on cabling and fuses to buy. Combo inverters and chargers have all the functionality of the separate units, but in one package. This AIMS unit isn’t actually just a charger, it’s a combo inverter AND charger. ![]()
