Portable Power Station Solution for a Russian Country House Backup Power System
1. Customer Requirement
The customer needs a reliable backup power solution for a country house in Russia. The equipment currently in use includes:
- Washing machine
- Refrigerator
- Dishwasher
- Electric stove
- Electric kettle
- 20 light bulbs
- 6 gas boiler circulation pumps
- Gas boiler electronic control unit
The key requirement is to keep essential household and heating-related equipment running during grid outages, especially in cold weather conditions where the gas boiler pumps and electronic control system must remain powered.
2. Recommended Solution
Recommended Model: EP12000 Portable Power Station
For this application, we recommend the EP12000 portable power station as the main backup power system.
The EP12000 is suitable for high-power residential backup scenarios because it supports:
- 12kW three-phase AC continuous output
- 11kW single-phase AC continuous output
- 10kW split-phase AC continuous output
- Built-in 7680Wh LiFePO4 battery
- Expandable capacity with extra battery packs
- UPS function with transfer time less than 10ms
- Multiple charging methods, including utility power, solar power, generator charging, EV charger input, vehicle charging, and wind power
- Smart monitoring via LCD panel and mobile APP
For a Russian country house, this configuration provides both high instantaneous output capacity and long backup runtime when combined with extra battery packs.
3. Load Assessment
The customer’s equipment includes both essential loads and high-power intermittent loads. The system should be designed with priority control rather than running all high-power appliances at the same time.
Essential Loads
These loads should remain powered during an outage:
For winter backup use, the gas boiler pumps and boiler control unit are the most important loads. If these are not powered, the heating system may stop even if gas supply is available.
High-Power Intermittent Loads
These appliances can be powered by the EP12000, but should be scheduled carefully:
4. Power Strategy
Recommended Operation Mode
To maximize runtime and system stability, we recommend dividing the loads into two groups:
Group A — Critical Backup Loads
These should be connected as the first priority:
- Refrigerator
- Gas boiler pumps
- Gas boiler electronic control unit
- Essential lighting
This group should remain powered continuously during grid failure.
Group B — Controlled High-Power Loads
These should be used one at a time when needed:
- Washing machine
- Dishwasher
- Electric stove
- Electric kettle
The EP12000 has sufficient output capability for high-power household appliances, but running several heating appliances at the same time may shorten runtime significantly. A practical usage rule is:
During an outage, keep the heating system, refrigerator, and lighting always on, and use the electric stove, kettle, washing machine, and dishwasher in separate time windows.
5. Why EP12000 Is More Suitable Than Smaller Models
For this customer’s equipment list, smaller portable power stations such as 3.6kW or 6kW models may be enough for lighting, refrigerator, and boiler control loads, but they are less suitable when the customer also wants to support high-power appliances such as an electric stove, dishwasher, washing machine, and kettle.
The EP12000 is a safer recommendation because:
-
Higher output headroom
The system can support large household appliances and motor-starting loads with more stability. -
Better for heating-related backup
The gas boiler pumps and electronic controller are critical in winter. The EP12000’s UPS function helps maintain power continuity when the grid fails. -
Expandable runtime
The built-in 7680Wh battery can be expanded with extra battery packs. Each EP12000B extra battery provides 11776Wh, and the total system can be expanded up to 372kWh. -
Multiple recharging options
In rural areas, charging flexibility is important. The system can be recharged from grid power, solar panels, generator, vehicle charging, EV charger input, and wind power. -
Suitable for harsh environments
The EP12000 is designed with LiFePO4 battery chemistry, thermal management, protective structure, and operating discharge temperature down to -20°C, which is important for Russian rural applications.
6. Suggested Configuration
Basic Backup Configuration
- 1 × EP12000 main unit
- Used for short to medium outages
- Priority loads: boiler pumps, boiler control unit, refrigerator, lighting
- High-power appliances used only when necessary and not simultaneously
Extended Winter Backup Configuration
- 1 × EP12000 main unit
- 1–2 × EP12000B extra battery packs
- Suitable for longer outages and winter heating backup
- Better runtime for boiler pumps, refrigerator, lighting, and limited appliance use
Long-Duration Rural Backup Configuration
- 1 × EP12000 main unit
- Multiple EP12000B extra battery packs
- Optional solar input or generator charging
- Suitable for remote houses with unstable grid supply or frequent outages
7. Practical Usage Scenario
When grid power fails, the EP12000 automatically switches to battery power and keeps the critical household loads running. The refrigerator, essential lighting, gas boiler pumps, and boiler electronic control unit continue operating, helping maintain heating and basic living conditions.
During the outage, the customer can still use high-power appliances such as the electric kettle, dishwasher, washing machine, or electric stove, but these should be used separately to avoid unnecessary peak load and to extend backup time.
If the outage lasts longer, the system can be recharged by a generator, solar panels, or other supported charging methods, making it suitable for rural residential backup where grid recovery time may be uncertain.
8. Key Selling Points for the Russian Customer

- Supports refrigerator, lighting, and essential home appliances
- High-power output suitable for electric cooking and household equipment
- LiFePO4 battery for safety and long cycle life
- Expandable battery capacity for longer winter backup
- UPS function for fast switching from grid to battery
- Multiple charging methods for rural and off-grid conditions
- Suitable for country houses, cottages, farms, and remote residential properties
9. Recommended Customer Message
Dear Customer,
Based on the equipment list you provided — washing machine, refrigerator, dishwasher, electric stove, electric kettle, 20 light bulbs, 6 gas boiler pumps, and the gas boiler electronic control unit — we recommend using the EP12000 portable power station as the backup power solution for your country house.
The most important backup loads are the gas boiler pumps, boiler control unit, refrigerator, and lighting. These loads are essential for maintaining heating, food storage, and basic living conditions during a power outage. The EP12000 provides high-output AC power and a built-in LiFePO4 battery, making it suitable for both essential backup loads and high-power household appliances.
The EP12000 supports 12kW three-phase AC continuous output, 11kW single-phase AC continuous output, and 10kW split-phase AC continuous output. It also has a built-in 7680Wh battery and can be expanded with extra battery packs for longer backup time. With UPS switching in less than 10ms, it can automatically keep important equipment running when the grid fails.
For daily backup use, we suggest keeping the refrigerator, lighting, gas boiler pumps, and boiler control unit connected as priority loads. High-power appliances such as the electric stove, electric kettle, washing machine, and dishwasher should be used separately during an outage to extend battery runtime and avoid unnecessary peak load.
For winter use in a Russian country house, we recommend at least one EP12000 main unit. If longer backup time is required, 1–2 extra battery packs can be added. Solar panels or generator charging can also be used as supplementary charging options for long-duration outages.
This solution provides a safer, quieter, and cleaner alternative to traditional fuel generators, while ensuring that the heating system and essential home appliances remain operational during unstable grid conditions.
