SRGFTS SUMRY Hybrid Solar Inverter Charger 3600W 24V→110V with 120A MPPT & 100A AC Charger

The SRGFTS SUMRY Hybrid Solar Inverter Charger is a 3600W pure sine wave inverter with an integrated 120A MPPT solar charge controller and 100A AC charger, designed to convert 24V DC to 110V AC for reliable off-grid and backup power.

This all-in-one unit combines inverter, solar MPPT charger and AC battery charger into a single enclosure so you can simplify installations, save space and manage energy flow between solar panels, batteries and the grid. With a 3600W continuous / 7200W peak inverter rating, wide PV input window and configurable charging priorities, it supports residential, workshop and mobile power setups. The LCD panel provides status and parameter control while built-in protections and silent cooling help maintain long-term operation.

How does the SUMRY inverter manage solar, battery and grid power?

The hybrid logic lets you set priorities so solar can power loads directly, charge the battery, or let the grid supplement when needed. When PV production is high the unit routes PV energy to the loads and battery first; when PV is low the system draws from battery or grid depending on your priority settings.

• Configurable priority: solar → battery → utility, or battery → utility.
• MPPT controller: 120A MPPT for efficient PV harvesting across 60–500V DC.
• Seamless transfer: automatic switching during outages or grid return.

What devices and batteries can it run and charge?

SUMRY outputs a pure sine wave 110/120VAC, compatible with most household appliances and many sensitive electronics within the 3600W continuous limit. It supports 24V battery banks including AGM, gel, lead-acid, lithium-ion and LiFePO4, and also includes a 100A AC charger to replenish battery stores when grid power is available.

• Rated 3600W continuous, 7200W peak for motor starts and surges.
• Compatible battery types: AGM, Gel, lead-acid, Li-ion, LiFePO4.
• AC charger at 100A for fast bulk charging from utility power.

How does it perform in solar-only or battery-less setups?

The inverter can operate without a battery when PV voltage is above the required threshold, allowing direct PV-powered loads. However, without a battery the system may rely on grid power if PV voltage dips or when panels cannot deliver sufficient wattage; adding a battery reduces grid draw and stabilizes output.

• PV-only operation requires PV input voltage to exceed roughly 120V under load.
• Max PV input power: 4200W with PV voltage range 60–500V DC.
• Battery recommended to prevent unintended grid consumption and supply transients.

What safety and control features help protect equipment and batteries?

The unit includes multiple built-in safeguards and a smart charging algorithm to extend battery life. An LCD provides real-time readings and lets you adjust charge current and operating parameters, while quiet fans and thermal management handle heat during sustained operation.

• Protections for overload, over-temperature, over-current and short circuits.
• Smart battery charging optimizes charge stages and prolongs battery lifespan.
• LCD display for settings and optional remote monitoring module available separately.

Who is this for? The SRGFTS SUMRY Hybrid Solar Inverter Charger is aimed at homeowners, small business owners, RV and boat owners, and off-grid builders who want a compact, integrated solution for converting 24V battery systems to 110/120VAC while managing solar input and reducing reliance on the grid. It suits users needing reliable pure sine wave output for sensitive electronics, support for high starting currents, and flexible energy routing between solar panels, batteries and utility power.
