Overview
Huayu's new affordable hybrid inverter HYH-3K-NA, continuous output power 3kW, surge power 6kW, is an Solar Inverter Charger that supports diversified energy management modes on solar/utility/generator charging, and utility/inverter power supply to the AC loads. Compatible with 48V battery banks, this solar inverter charger has the ultimate control with Three charging modes: Solar only, Solar priority, Utility & Solar, and two AC output modes: Utility priority and Inverter priority maximize energy utilization that make your system into an uninterruptible power supply (UPS), automatically switching to Off-Grid Mode in not more than 10 milliseconds to keep loads securely powered.
Product Highlights
- Five smart working modes, switch for different demand automatically
Three charging modes: Solar only, Solar priority, Utility & Solar, and two AC output modes: Utility priority and Inverter priority maximize energy utilization, or it will automatically switch the working mode according to the actual situation to realize the uninterrupted power supply.
- Pure sine wave output
With advanced SPWM technology and pure sine wave waveform, it outputs very low harmonic distortion and clean power like utility-supplied electricity, and let your Inductive loads like microwave ovens and motors run faster, quieter and cooler.
- ALL-IN-ONE hybrid system
Integrated with 80A/220V MPPT solar charge controller, 3000W pure sine wave inverter, and 40A battery charger in one compact unit to let you enjoy the stable power from the sun and the utility grid to keep you powered under any circumstances.
- Seamless switching under 10ms
In the event of AC Charging or solar charging failure, the Inverter charger will takes over the supply to the alternative option less than 10ms, which will keep your electronics working.
- Multiple safety protection mechanisms
Equipped with multiple and complete software and hardware protection, including short circuits, over voltage, overload, over charge, over temperature, high current, reverse, etc., to ensure the uninterrupted normal operation of your system.
- Extensive battery matching
Preset battery mode for 48V SLA, AGM, GEL, Water, and Lithium batteries, or choose Customize type to match your battery.
In addition to the above outstanding advantages, this inverter charger has a very competitive price advantage over the same type of energy storage inverter, and can be widely used in villas, outdoor outings, camping, RVs, and household electricity with unstable grid. Equipped with multiple features and modes, the Huayu Inverter Charger is a powerful addition to any 48V system!
System Diagram



Q: Can the inverter work with lithium battery without communicating with BMS?A: Yes. The inverter can work with a lithium battery without communicating with BMS. However, the real-time monitoring data and protection point will be the sampling data from the inverter. But the user has to set the voltage set points of the inverter according to the data of the BMS, or it will cause the charging abnormal.
Q: Can the inverter operate with PV or Utility only, but without battery?
A: Yes, it has no No-Battery mode. The parameters can be set without a battery connection.
Q: Can I use this inverter to charge my batteries?
A: Yes. Compatible with 48V battery banks, this solar inverter charger keeps your battery charged with solar panels and AC/generator.
Q: Is the Max. charge or discharge current settable?
A: Yes. This series can not only set the total charging and discharging limiting current of the battery but also set the charging current of the utility. Users can flexibly configure the utility according to the demand.
Q: What size inverter should I buy?
A: Sizing the right power output.
Make sure your inverter charger can handle at least 1½ times the load of continuous demand you expect to have regularly. To figure this out, simply add up the wattage of each device you plan on running simultaneously. Be sure the inverters you’re considering will be able to supply enough AC power.
B: Check your battery voltage.
The DC voltage rating on the inverter will tell you what battery bank it is compatible with. For example, a 48V battery bank will require an inverter that is compatible with 48V DC input.
C: Size your installation spaces.
Make sure the inverter will fit in the space you have in mind with enough room around it for proper ventilation and no fire hazards.
D: Remote operation is important.
Huayu pure sine inverters come with convenient remote control and APP options so that you can operate the unit from afar.
