Off grid Solar Inverter Charger
Transforming power with safety and adaptability
Wall-mounted structural design; Grid-tied/Off-grid Dual Modes; Sine wave output, with an output power factor (PF) of 1; Standard 8500W high-voltage MPPT controller; Maximum battery charging current: 120A; 98% PV Conversion Efficiency; Supports inverter operation without a battery.
6200W Peak Boost for Inductive Loads
Unlimited load capacity can be achieved through proper wiring, free from the inverter's inherent power limit.
Grid-tied & Off-grid Operation
Grid-connected Power Selling Available in Battery Mode;
Added Battery-to-Grid Function with SUE & PEC Modes: Store and Sell as Needed
Newly upgraded Silicon carbide process
Low heat loss and high efficiency;
Compared with traditional silicon-based materials, it offers higher conductivity, more stable operation and lower self-loss.
CT Anti-backflow Protection
CT-based anti-back flow monitoring intelligently regulates current direction, prioritizes self-use, prevents backflow, ensures compliance and saves energy costs.
Satisfies the household's need for high-power electricity consumption
It automatically monitors and adjusts load distribution in real time. You can enjoy stable power supply without the risk of equipment damage or power outages.
Multiple Function Upgrades to Meet Higher Requirements
PV Max Input Power is 8500w; Peak Output Power is 12276w; 98% PV Conversion Efficiency
Intelligent recognition charging with built-in lithium battery activation function
Smart lithium battery activation, supports over-discharge restart, compatible with lithium batteries of multiple brands for easy matching and use.
Strong Adaptability to Extreme Environments
From scorching deserts to freezing highlands, from humid coastal areas to dusty plateaus, our inverters and energy storage systems deliver consistent, reliable performance. They stand firm against harsh conditions that challenge ordinary equipment.
Relatively Quiet Operation
Our energy storage system operates at a mere 50dB, a volume softer than the rustle of wind through leaves or a gentle conversation in a living room.
Inverter Application Scenarios
Residential, Industrial, Photovoltaic (PV), RV Power Supply, Outdoor Camping / Camping &, Outdoor Adventures, Island & Fishing Boat and so on.
