Pure Hybrid Solar Inverter

SUMRY HGX 4KW Pure Sine Wave Hybrid Solar Inverter – 24V Off-Grid Power with 140A MPPT

You need reliable power when the grid fails or you live off-grid. This SUMRY hybrid inverter delivers clean, stable electricity to your home, cabin, or boat. The built-in 140A MPPT solar charger pulls maximum energy from your panels, so your battery fills faster. You manage every setting right from the responsive 6.25-inch LCD touchscreen.

• 4000W Pure Sine Output: Provides smooth 110-120VAC current that safely runs sensitive electronics and appliances.
• 140A Solar Charging: Accepts up to 5600W PV input to rapidly charge your 24V battery bank from sunlight.
• Smart Battery Support: Optimizes charging curves for LiFePO4, Lithium, Gel, AGM, and lead-acid packs.
• Intelligent SBU Mode: Seamlessly blends solar, battery, and utility power for uninterrupted backup supply.
• Durable Glass Cover: Resists dust, moisture, and scratches for long-lasting performance in harsh environments.

Product Description

This SUMRY HGX series inverter combines three essential functions into one compact unit. You get a pure sine wave inverter, an MPPT solar charge controller, and a smart battery charger working together. Your system automatically prioritizes solar power to save money. The high PV input range of 55V to 350Vdc accepts a wide variety of panel configurations. You can configure AC or battery input priority directly on the display.

Product Overview

Designed for off-grid living and emergency backup, this device bridges solar energy storage and household power. It fits perfectly in RVs, tiny homes, telekom shacks, or residential backup systems. You enjoy seamless switching between sources without interrupting your load. The machine supports cold restarts, meaning it boots up even when battery levels are critically low.

Key Benefits

Your appliances run quietly and efficiently because the pure sine wave output mimics municipal power. You reduce fuel consumption by letting solar and battery handle daily loads instead of a generator. Automatic restarts resume operation the moment solar generation recovers after clouds pass. Built-in overload, over-temperature, and short-circuit protections keep your entire system secure.

Features

• Tailorable Working Modes: Choose from Only Solar, Solar First, or Mains & Solar charging profiles to match your energy habits.
• Remote Monitoring Ready: Add an optional WiFi module to track battery stats and power flow from your smartphone.
• Voice-Command BMS Link: Communicate with smart batteries via PACE or PYLONTECH protocols for precision management.
• Cold Start Capability: Power on your equipment immediately, even if the batteries report empty or disconnected.
• One-Click Reset: Restore default factory settings instantly to resolve configuration errors quickly.

How to Use

Connect your battery first using a 2P200A circuit breaker. Verify the battery reads near 24V before proceeding. Attach your solar array via a 2P20A breaker and close the switch. The display lights up, indicating the MPPT charger is active. Press the bottom-right power button to start the inverter. Confirm AC output voltage, then install breakers for utility input and final output as specified. Configure your preferred charging modes through the touch interface.

Customer Benefits

Eliminate anxiety during blackouts with instant transfer to battery power. Lower your monthly electric bill by storing cheap daytime solar for peak evening usage. Extend the lifespan of your lithium bank with intelligent charging algorithms tailored to modern batteries. Monitor system health remotely to catch issues before they cause downtime.

Ideal Uses

Powers vital home circuits including refrigerators, TVs, LEDs, and ceiling fans. Runs portable offices or workshops where grid access is unavailable. Supports water pumps, sump pumps, and security systems for peace of mind. Charges drones, tablets, and laptops via USB outputs on select setups.

Who It's For

Homeowners transitioning to renewable energy who want budget-friendly backup. Off-grid travelers seeking lightweight, silent power solutions. DIY solar enthusiasts building custom installations with mixed battery chemistries. Small business owners protecting point-of-sale systems and medical devices.

Frequently Asked Questions

• Does this inverter operate without a battery connected? Yes, the unit supports run-without-battery function, allowing you to test PV and AC inputs directly for maintenance or temporary off-grid power.
• Can I view real-time data on my phone? Absolutely. By purchasing the compatible optional WiFi module, you can connect to the inverter via RS232 to monitor voltage, current, and status remotely.
• What breaker sizes do I need for installation? We recommend a 2P200A breaker for the battery, 2P20A for PV input, 2P63A for utility AC input, and 2P40A for the inverter output.
• Is it safe to use with induction motors like HVAC units? The pure sine wave output ensures smooth startup for inductive loads such as motors and compressors, provided their surge requirements stay within the 4000W rating.
• How does the SBI mode differ from SBU mode? Select SBU mode to allow power transfer to the grid during outages, or choose SBI mode if you require electrical isolation from the utility line for safety.
