All-In-One Off-Grid Energy Storage System (3kW / 5kW)

Our All-In-One Off-Grid Energy Storage System is a next-generation power solution designed for residential energy independence, remote cabins, and critical backup power. This commercial-grade system seamlessly integrates a high-efficiency off-grid pure sine wave inverter, an advanced MPPT solar charge controller, and an ultra-safe Lithium Iron Phosphate (LiFePO4) battery pack into a single, compact, and wall-mounted enclosure.

Engineered for both newly installed DC-coupled systems and existing off-grid retrofits (photovoltaic capacity increase), it eliminates complex wiring, minimizes installation space, and provides stable, reliable power wherever grid access is limited or unavailable.

Our integrated ESS is highly versatile and optimized for various off-grid and backup power scenarios:

• Residential Microgrids:

  Perfect for residential energy storage, enabling homeowners to maximize solar self-consumption and achieve full grid independence.

• Emergency Power Backup:

  Provides immediate, reliable backup electricity for areas prone to unstable utility grids, severe weather, or frequent power blackouts.

• Solar Expansion & Retrofitting:

  Highly compatible with existing solar installations to increase photovoltaic storage capacity or convert grid-tied systems to off-grid hybrid setups.

• Recreational Vehicles (RVs) & Marine:

  Utilizing the specialized RV Priority Mode to power mobile off-grid living with stable AC output.

3. Seamless Power Transfer

   <5ms switch time, no interruption to loads.

4. Adjustable Parameters via LCD

   Output voltage, frequency, charging current, battery protection points configurable.

5. PV & AC Hybrid Charging

   Support solar, utility or combined charging.

6. Full Safety Protection

   Over/under voltage, over current, over/low temp, short circuit, overload protection.

7. Intelligent Fan Control

   Automatic speed adjustment for quiet and efficient cooling.

8. Bluetooth Monitoring

   Real‑time battery and system status view.

• Integrated Plug-and-Play Design:

  Combines the inverter, MPPT charger, and LiFePO4 battery module into a single unit. This pre-configured system dramatically reduces on-site installation labor costs and prevents wiring errors.

• Industrial-Grade Safety & Reliability:

  Built with standard-certified LiFePO4 (Lithium Iron Phosphate) chemistry enclosed in a hermetically sealed metal case. Fully compliant with UN 38.3 regulations, featuring explosion-proof safety valves.

• Ultra-Fast UPS-Level Transfer:

  Features an industry-leading switching time of less than 5ms (<10ms in programmable UPS mode), guaranteeing that critical home loads, appliances, and computers experience zero disruption during unexpected power blackouts.

• Intelligent Operating Modes:

  Pre-programmed with Four Flexible Working Modes—Utility Priority, Battery Priority, Energy-Saving (Eco Mode, active at loads <25W), and RV Priority Mode to optimize self-consumption and maximize ROI.

• Smart Bluetooth & LCD Interface:

  Real-time parameter query via a comprehensive LCD panel. Built-in Bluetooth allows installers and end-users to effortlessly monitor battery grouping, temperature, and SOC status.

• Advanced Protection Suite:

  Equipped with automatic charging over-voltage, discharging under-voltage, over-current, short-circuit, and dual-layer high/low-temperature thermal protections.

A: Yes. The AOLES-3KW and AOLES-5KW systems are specifically engineered for dual-purpose applications. They can be installed into brand new DC-coupled solar microgrids or utilized as an off-grid retrofit / photovoltaic capacity increase solution for pre-existing systems.

A: The system delivers an ultra-fast switching time of less than 5ms under standard conditions. When programmed into dedicated UPS mode (typical 10ms transfer), it ensures a completely uninterrupted power supply for sensitive devices like computers, servers, and home appliances, preventing any data loss or system resets.

A: The system supports four customizable prioritization modes via the LCD menu:

1. Utility Priority Mode (GRD):

   Uses grid power to support the load first; switches to battery when utility fails.

2. Battery Priority Mode (PBG):

   Minimizes grid reliance by using solar and battery power first.

3. Energy-Saving Mode (PWS):

   Intelligently saves power when the home load drops below 25W by briefly pausing output.

4. RV Priority Mode:

   Customized AC output priority designed dynamically for mobile applications.

A: Safety is our highest priority. The battery cells are sealed in a heavy-duty metal enclosure equipped with individual explosion-proof valves. The built-in Battery Management System (BMS) offers complete automated protection against charging over-voltage, discharging under-voltage, short-circuits, and smart variable fan-speed thermal controls. The cell pack is strictly UN 38.3 certified for safe global transport.

A: This energy storage system is an indoor IP20-rated version. It must be wall-mounted in an environment with relative humidity between 10% and 95% (non-condensing) and ambient temperatures ranging from -20°C to 55°C. It should not be installed in unventilated wall cavities, habitable bedrooms, or locations prone to direct rainfall.
