go power 3,000 watt inverter charger

Combining an inverter, converter charger, and transfer switch, the Go Power IC Series 3,000-watt inverter charger puts three essential RV functions into one unit. The compact size takes up less space in your RV and simplifies installation. It lets you convert AC shore power into DC power to charge your batteries, inverts your DC battery output into AC power to power electronics and appliances, and automatically transfers to shore power when available.

Pure Sine Wave Inverter Produces Clean AC Power

The pure sine wave inverter changes DC output from your RV batteries into AC power and sends it to the electrical system. It creates clean power with low distortion, making it safe, efficient, and perfect for sensitive electronics like computers. Plus, the inverter can generate 4,800 starting watts and 3,000 running watts which is a great fit for larger appliances or multiple devices.

Smart Converter Charger with Automatic Multistage Charging System

The smart converter charger converts AC shore power into DC power to charge your battery bank. If your RV already has a stock converter charger, it will need to be removed to ensure this part of the unit operates properly.

Using a multistage charging system, the converter charger automatically switches voltages while the battery bank charges. This accelerates the charge, but also helps extend battery life by adjusting the voltage during the different modes. It is compatible with sealed/gel, AGM, flooded/wet cell, and lithium batteries. And with the optional fixed-mount remote (sold separately), you can select charging profiles for the different battery types.

Charging Modes

  1. Bulk: This mode charges at the full rated load for a quicker recharge time. As the name suggests, this is where the bulk of the charging happens. It typically charges the battery to at least 80% capacity.
  2. Absorption: This mode provides controlled voltage to ensure a full charge. Once the battery reaches between 80% to 90% capacity, the absorption state will kick in and start charging at a regulated voltage. This mode is set to last for 2 hours after the bulk charge is completed.
  3. Float: Once the battery reaches full charge, this mode maintains a lower voltage to compensate for self-discharge. This reduces battery stress and minimizes gassing and water loss.
  4. Equalization: On flooded batteries, this mode (which is only accessible with the optional fixed-mount remote) activates to prevent stratification and sulfate buildup during extended float cycles. These two issues can damage a battery by causing the accumulation of acid at the bottom of the battery and hardened sulfate crystals on the battery plates. This mode is especially helpful when your battery is going unused during storage.

Automatically Switches to Shore Power

The integrated transfer switch selects the primary source of AC current. The switch inside of this inverter charger has been pre-wired to automatically change from inverter to shore power to conserve battery life. This switch includes (2) 50-amp legs, which allows you to use up to 100 amps by passing through 12,000 watts on a shore power service. The legs are rated at 120V each, but they can be used as a 240V split-phase or 240V dual input if needed. This would be useful if your RV has larger appliances, such as a clothes dryer or oven range. However, if you plan on using an on-board generator and shore power, you still need an external transfer switch to link power to the inverter charger. If you are just utilizing shore power, you only need this unit since you are switching between two sources.

To prevent electrical interruptions, the time delay circuit board allows the alternate power source to stabilize before a transfer occurs. Additionally, since the switch only accepts one active source, it protects your electrical system from dangerous backfeed that can damage your equipment.

Connections and Status Lights

inverter charger terminals

The inverter charger includes AC input and output terminals that connect to your AC panel and shore power input. It has DC input terminals which connect to your batteries. Additionally, it has ports for the fixed-mount remote and battery sensor. It also has 2 LEDs that show fault conditions and operation mode. Lastly, it has a power switch that controls the inverter charger.

Safety Features

Built-in safety features help protect your RV's electrical system. They offer protection from over/under voltage and overloading. The inverter also uses a heat sink process to protect from extreme temperatures, and an internal cooling fan removes excess heat from the unit.

fuse installation

For additional safety, installing a fuse between the battery bank and the inverter charger will protect your equipment from power surges. The Go Power 400-amp fuse block (sold separately) works with this unit and uses a slow blow time-delay feature to withstand surge current. This means it can handle short surges over 400 amps without blowing the fuse, which is great for devices with motors that require more energy to start.

Battery Temperature Sensor Adds Additional Battery Protection

battery temp sensor

The battery temperature sensor protects the battery bank from large temperature fluctuations. As the inverter charger experiences changes in temperature, the sensor compensates for those changes by adjusting the voltage during charging to help extend the life of your batteries. This protects from overcharging in hot temperatures and undercharging in cold temperatures. The voltage adjustments also ensure that you are getting the most from your charge.

How It Installs

The inverter charger mounts inside your RV in a dry location with ventilation. It should be installed in close proximity to the battery bank, but not in the same compartment. The DC terminals are wired to the battery bank. There are several ways to connect the inverter section to your RV's electrical system, but this will depend on your rig and how you want to use your inverter. Also, the temperature sensor installs to the negative battery terminal and plugs in the battery temperature port on the inverter charger.

Available Fixed-Mount Remote

The optional fixed-mount remote (sold separately) lets you monitor and control the inverter charger from inside your RV. It includes a digital display that shows the voltage, output power, status, temperature, and charging activity. You can also customize settings like your battery profile, charge rate, and more. And it has a power button that lets you turn the inverter charger on and off.

Speaker 1: Today we're going to take a look at the Go Power! 3000W industrial pure sine wave inverter and inverter charger. Now, this has a 3 in 1 system, which will combine your inverter, your battery charger and automatic transfer switch. The combined system will save you space, while simplifying installation, 'cause you have less devises and wiring. This is power factor corrected, uses industry standard protection features, and it is compatible with 30 amp service.It includes everything laid out here on the table, the inverter charger itself, two of the DC terminal covers, one red, one black, that you just mount right on there, to protect your battery cable connections, two ring lugs that you'll attach to your battery cables, to install it onto the inverter and a 25ft cable right over here, that has a battery temperature sensor on the one end.Basically, the temperature sensor will mount onto your battery. The other end, right here, will plug into the inverter charger, and the temperature data will help adjust the voltage, to maintain proper charging of your battery. Now, on one side here, you can see at the very bottom, it has two AC input circuit breakers, has an AC access cover right here, has a handle here and one on the other side.

It makes it very easy to pick up the inverter.Other side over here, just has some air vents on it. Then on the ends, right here, on this end it'll have a AC entry and an AC exit terminal, has a DC ground, right down here. Right in the middle here, you'll have a remote control port, battery sensor port and some status lights. At the very top, there's a little on and off switch. Over here is your negative and positive DC terminals.Now on the inverter use, it's continuous output power is 3000W.

Peak surge power is 4,800W for five seconds. Current peak output is 52 amps, continuous output is 25 amps. AC output voltage is 115V. AC connections are a split phase-in, dual-out, and then dual-in and dual-out. Has an input voltage range of 9V to 17V DC.

Maximum continuous DC input current of 400 amps, and the AC output wave from is a pure sine wave. Maximum efficiency is 90%, and the no-load power consumption ,in a normal mode, is 25W and the sleep mode is 5W. When used as a charger, the input voltage is nominal, a a 120V AC. The range is 80V to 140V, AC. Input current is 18 amps.

Optimal efficiency is greater than 85%. Charge control, it's 3 stage, with manual equalized. Output voltage is 5V to 60V DC. Output current is 125 amps. Then you can, right here, change temperature compensations that uses the remote battery sensor.Weight on this item is just under 50lb, about 49.8lb. The width on it, we're going to measure from here to the furthest part that sticks out, so it's going to be 15" long. The width on it is going to be 11-1/8" wide, and the depth on it is right at 8" deep.Also comes with this nice users manual, which will describe how to install everything and how to use it.That should do it for the review on the Go Power! 3000W industrial pure sine wave inverter and inverter charger.

Review from a similar Go Power Pure Sine Wave in RV Inverters

The product itself so far so good. Customer service was good. BUT I thought the # 34277742 switch for my inverter was included with the inverter, I even e mailed the ad to separate sales guys showing them that their ad says the switch is included, bottom line I was out more money for a switch, extremely disappointing, seems like false advertising but what can you do. 672442

As mentioned in the product description above, the remote switch is sold separately.

  • How To Wire Two 6 Volt Batteries On a Motorhome And Hook Up Inverter
    I have attached a photo for you on how a set of two six volt batteries should be wired on a motorhome. It does indeed sound like your batteries are wired correctly so I do not think you need to worry about this. The positive lead from battery one is going to be run to the inverter and the negative lead from battery two is going to be run to the chassis ground.

  • How to Create Auxiliary Power System in Enclosed Trailer
    I'll try to start this answer off with some of the most important information- the batteries. The batteries you will need to power all of this would need to be 12v deep-cycle batteries with enough amp hour rating to power all of the tools and lights for an extended period of time; since we don't sell batteries, I don't have a specific recommendation but something with a 100 amp hour rating (you'll likely need multiple batteries wired in series to supply enough power to make this work)....

  • Will Two 12V Batteries be Enough to Power the 3000W Go Power Inverter # 34275013 for a Short Time
    You can use two 12V batteries to power the Go Power Inverter # 34275013 but that all depends on what size 12V batteries you plan on using what "short periods of use" means. I reached out to my contact at Go Power and he said that if you are using deep cycle batteries and the load is not too excessive then you should be fine. For example, if you were trying to pull the full 3000 Watts out of the inverter that would be about 26 Amps AC or 260 Amps DC. If you were to run this for a half...
