The EasySolar-II 48/5000/70-50 GX inverter is an all-in-one solution for off-grid and hybrid power systems that combines:
-
MultiPlus-II 5000 VA / 4000 W inverter, 9000 W peak
-
Mains/generator charger, 48 V, 70 A
-
SmartSolar 250/100-Tr MPPT controller for up to 5.8 kW of active solar generation
-
GX controller with Wi-Fi, Ethernet, VE.Direct, USB, BMS-Can, and display
-
230 V 50 A grid/battery transfer switch that provides 7.35 kW of power through the inverter
This device is ideal for ESS systems, residential buildings, mobile energy solutions, small businesses, and telecom infrastructure, ensuring reliability, continuity, and full control.
Key Benefits of the EasySolar-II Inverter
- Inverter rated power: 5000 VA / 4000 W, peak — 9000 W
- MPPT 250/100 — up to 5800 W of solar power, up to 250 V Voc, efficiency up to 99%, the controller withstands overloads of up to 300% of the solar panel power
- Integrated GX controller – parameter display, Wi-Fi, VE.Bus, VRM, get full control via the internet, including software updates, full configuration changes, push notifications to your phone, and support from the “Total-Energo” LLC service center
- 48 V 70 A charger + temperature compensation – supports any type of battery, including modern lithium (LiFePO4) batteries
- Zero-load consumption: from 18 W to 2 W (in Search Mode) — virtually no self-consumption, does not discharge batteries without a load
- PowerControl and PowerAssist — balancing of the generator and the grid, ensuring that the input circuit breaker never trips or the fuel generator overloads
- Perfect compatibility with LiFePO₄ batteries; BMS-CAN support allows you to connect the inverter, charger, and MPPT controller to the battery’s BMS using a single cable. Enjoy complete safety when using lithium batteries.
- Temperature range: –20…+45°C, active ventilation—suitable for installation in vehicles, mobile systems, outdoor enclosures, and unheated rooms
- Compact housing (604 x 323 x 253 mm), weight – 38.6 kg.
Technical Features
Integrated GX controller: display, network, remote access
- 2-line display showing battery, solar, and inverter readings
- Wi-Fi + Ethernet for connection to VRM
- USB and VE.Direct — monitoring, updates
- BMS-Can — communication with lithium batteries
MPPT 250/100 SmartSolar — efficient solar control
- up to 5800 W from 1 MPPT, expansion up to 300% of PV power
- 3-stage charging: Bulk / Absorption / Float for LiFePO4 batteries
- Ideal for 48-cell panels, tracking with partial shading
PowerAssist® + PowerControl®
- PowerControl limits consumption from the generator or grid
- PowerAssist adds power from the battery during peak loads
- Ideal if you have a weak power source
Victron ESS Smart Energy System – integrated into EasySolar-II
Supported modes:
1. Grid in-line:
- PV charges the battery or supplies power to the load
- If PV is insufficient – power from the battery or grid
- If the grid goes down – automatic switch to battery backup
2. Grid parallel:
- PV + grid + battery = optimal self-consumption
- Supports energy efficiency with current analysis (via external sensor)
- ESS does not allow power to be fed back into the grid (unless required)
- Supports connection to the green tariff (if required)
3. Back-up only / off-grid:
- Full autonomy, critical loads are always powered
- Priority: PV → battery → generator
LiFePO₄ support with BMS – safety and durability
EasySolar-II GX has a built-in BMS-Can interface, which provides:
• Complete safety: protection against overcharging, overvoltage, and overheating
• Smart monitoring: SOC, voltage, temperature
• Adaptive charging parameters
• maximum battery lifespan, compliance with manufacturers’ warranty requirements
Use Cases
- Homes with solar power stations — up to 5.8 kW of generation, backup
- Campers, summer homes, cottages — autonomous “all-in-one” system
- Offices, service centers, small businesses — uninterruptible power supply
- Telecom, remote sites — backup for critical loads
- ESS with self-consumption and tariff support
Communication interfaces
- VE.Bus – Parallel/three-phase operation, connection to GX devices, external display, external control panel, etc.
- VE.Direct – Connection to external MPPT controllers, connection to SmartShunt and BMV battery monitors
- BMS-Can – Communication with lithium batteries (Sacred Sun, Sunlight, BYD, Pylontech, MG Energy, etc.)
- Wi-Fi / Ethernet – Remote control and updates via the VRM cloud service
- USB – Connection to a PC, firmware updates, expanded functionality via USB hubs
- Programmable relay – Generator start, emergency shutdown
