Description
The sun is the cheapest fuel on earth, and the Sun Bridge is the machine that turns it into a household currency. This 4kW hybrid solar inverter converts raw photovoltaic energy into clean, pure sine wave power for the loads that matter: refrigerators, pumps, tools, and electronics. With a 98% peak conversion efficiency, it wastes almost nothing of what your panels harvest, making every watt of solar capacity count twice.
At its heart is a 100A MPPT charge controller with a 60-500VDC operating window, which means it can harvest energy from high-voltage solar arrays that smaller controllers cannot even see. The hybrid architecture lets it work in both off-grid and grid-tie modes, switching intelligently between solar, battery, and utility power so your loads never notice the seam. It will even run your loads without a battery attached, feeding solar directly to the appliances during daylight hours.
Communication is where this inverter stops being a box and becomes part of your nervous system. RS232, RS485, and built-in WiFi interfaces stream live generation, consumption, and battery telemetry to your phone, so you can watch your system earn its keep in real time. With CE certification and support for automatic lithium battery activation, The Sun Bridge is the control center that turns scattered panels into a unified power plant.
Key Features
- ✦ 4,000W rated output with pure sine wave: clean, appliance-safe power for inductive loads like fridges, pumps, and motors.
- ✦ 100A MPPT solar charger with 60-500VDC range: harvests from high-voltage arrays with up to 98% conversion efficiency.
- ✦ Hybrid off-grid / grid-tie operation: automatically blends solar, battery, and utility power without interrupting your loads.
- ✦ Battery-free operation supported: runs loads directly from solar during daylight, ideal for temporary or budget setups.
- ✦ WiFi / RS232 / RS485 monitoring: real-time system telemetry on your phone, including generation, load, and battery state.
- ✦ Automatic lithium battery activation: wakes dormant LiFePO4 packs so the system recovers from deep protection events on its own.

Where It Works
The Sun Bridge is the command center for serious solar: a remote workshop running on a 24V battery bank, a farmhouse off-grid system feeding pumps and refrigeration, a grid-tied home that wants to shave its utility bill, or a mobile setup in an RV or container that needs reliable sine wave power. The 100A MPPT controller pairs naturally with the Grid Reserve and Power Vault LiFePO4 batteries, forming a complete EastSupplier solar ecosystem from panel to appliance.
Frequently Asked Questions
Q: Can this inverter run my home appliances?
A: With 4,000W of pure sine wave output it comfortably runs refrigerators, freezers, washing machines, power tools, TVs, and lighting. Check the starting surge of large motors against the inverter's peak rating for the heaviest loads.
Q: Does it work with lithium batteries?
A: Yes, it supports LiFePO4 and other lithium chemistries, including automatic activation of lithium packs that have entered protection mode. Select the matching battery type in the settings.
Q: What is the advantage of the 100A MPPT charger?
A: A 100A charge current lets you feed a large solar array into a modest battery bank quickly, and the 60-500VDC input range works with high-voltage series arrays that deliver more power with thinner, cheaper cabling.
Q: Can it operate without a battery?
A: Yes, it supports battery-free operation, running loads directly from solar during daylight hours. This is useful for temporary installations, though a battery is required for night-time or cloudy-period operation.
Q: How do I monitor the system?
A: The built-in WiFi interface connects to the manufacturer's monitoring app, showing live solar generation, battery state of charge, load consumption, and system alerts on your phone. RS485 is also available for third-party monitoring.
Q: What is the difference between off-grid and grid-tie mode?
A: Off-grid mode makes the inverter the sole source of power for your loads; grid-tie mode lets it synchronize with utility power, prioritizing solar and battery while drawing from the grid only when needed.
This is not an inverter. It is the bridge between sunlight and switch-flip certainty.
