All-in-One 3KW Off-Grid Energy Storage System | 51.2V 5.12KWh LiFePO4 Battery

All-in-One 3KW Off-Grid Energy Storage System | 51.2V 5.12KWh LiFePO4 Battery

The GreenMore All-in-One 3KW Off-Grid Energy Storage System integrates a 3000W pure sine wave inverter with a 5.12kWh LiFePO₄ battery into a single compact unit, delivering reliable off-grid power for homes, farms and small businesses.

The built-in MPPT charge controller (80–450V input range, 3000W max PV) maximizes solar harvest, while the EPS function provides seamless 10ms switching between solar and battery modes — keeping critical loads running without interruption. Supporting parallel connection of up to 32 modules (expandable to 163.84kWh), the system scales from a single-family home to a small commercial facility. WiFi and GPRS communication enable real-time mobile app monitoring from anywhere, with remote diagnostics and OTA firmware updates. Certified to CE, IEC62619, MSDS and UN38.3, the off-grid energy storage system delivers safe, intelligent and sustainable clean energy management for residential and light commercial projects across our target markets.

Application Scenarios

Off-Grid Residential Homes

For remote, island, mountain and rural homes without grid access — start with one 5.12kWh unit for basic loads and scale to 32 units for full-home electrification including air conditioning and cooking.

Agricultural & Farm Operations

Powers irrigation pumps, electric fences, barn lighting, milking machines and workshops where grid extension is too costly. 6000VA peak handles pump and compressor surges; IP54 suits dusty sites.

Telecom & Remote Monitoring

24/7 power for base stations, weather stations, pipeline points and security cameras. WiFi/GPRS enables centralized management of distributed sites; 10ms EPS guarantees zero downtime.

Small Commercial & Eco-Tourism

Eco-lodges, glamping sites, remote offices, shops and clinics run fully off-grid. Quiet ≤60dB cooling suits guest areas; multiple units parallel for higher demand with app monitoring.

Safety & Quality Assurance

LiFePO₄ Chemistry

The safest mainstream lithium chemistry — inherently thermally stable with no thermal runaway risk, built from eco-friendly, non-toxic materials for environmental compliance.

Comprehensive BMS Protection

Over-charge/discharge, over-current, short-circuit and over-temperature protection with real-time cell monitoring (44.8–58.2V, 100A limits) at cell, module and system level.

Certifications & Compliance

CE, IEC 62619, MSDS and UN38.3 certified by internationally recognized laboratories, covering product safety and global shipping requirements.

FAQ

Q1: What does "all-in-one" mean?

Inverter, MPPT controller, BMS and LiFePO₄ battery share one floor-standing enclosure. Just connect panels and loads — less wiring, lower cost, no compatibility issues.

Q2: How many modules can run in parallel?

Up to 32 modules — from 5.12kWh to 163.84kWh. Start with one unit and add more as demand grows, for homes or small commercial sites.

Q3: Can I monitor it remotely?

Yes — built-in WiFi/GPRS and a mobile app show SOC, power flow, PV generation, faults and system health anywhere, with remote diagnostics and OTA updates.

Q4: What happens in a grid outage?

EPS switches to battery within 10ms (UPS mode; 20ms for appliances). Refrigerators, routers, lighting and security stay on; 6000VA peak absorbs load surges.

Q5: Does it work with no grid at all?

Yes — designed for pure off-grid operation. Solar is the only energy source, with 3000W MPPT charging and 3000VA / 6000VA output for homes, farms or remote facilities.

Q6: What warranty and support is included?

Every off-grid system carries a 3-year warranty, WiFi/GPRS remote diagnostics, on-site support through our distributor network, and rapid module replacement. Extended coverage for large projects.

Q7: Do you support OEM/ODM?

Yes — custom capacity, enclosure color and branding, protocol adaptation and logo printing. Engineers work directly with installers and distributors. Contact our team with your requirements.
