Portable Power Solution for RV Travel and a Five-Room Small Network System

1. Understanding the Customer’s Needs: RV Power + Five-Room Network Backup

The customer’s requirements can be divided into two scenarios.

1.1 RV Living Power

RV power demand usually has the following characteristics:

• Multiple types of electrical devices: refrigerator, lighting, water pump, air conditioner, induction cooker, microwave, coffee machine, laptop, photography equipment, and communication devices.
• Some devices have high startup power: air conditioners, compressors, water pumps, and power tools may create surge loads during startup.
• Low noise is important: campsites, night use, and natural outdoor areas are not suitable for long-term fuel generator operation.
• Charging sources vary: power may come from campsite utility power, solar panels, vehicle charging, generator charging, or temporary charging stations.
• Mobility is required: the power station may need to move between the RV, outdoor campsite, and temporary work area.

1.2 Five-Room Small Network Power

A small network across five rooms is closer to a compact low-voltage or communication system. It may include:

• Main router, optical modem, or 5G CPE
• Network switch or PoE switch
• Access points, cameras, or small terminals in each room
• NAS, small server, access control, or security host
• Cabinet cooling fans and emergency lighting

This type of load is not necessarily high-power, but it is highly sensitive to power interruption. A short outage may cause network disconnection, loss of surveillance recording, remote-work interruption, or manual equipment restart. Therefore, the key requirement for the network system is not peak power, but long-duration stable output and UPS-level switching.

2. Recommended Solution 1: Heavy-Duty RV Power — EP12000 as the Core Power Platform

If the customer’s RV power demand includes air conditioning, induction cooking, microwave use, power tools, or the need to support outdoor work and emergency EV charging, EP12000 should be the preferred core power source.

Why EP12000 Is Better for Heavy-Duty RV Use

EP12000’s main advantage is the combination of high power, large capacity, and expandability:

• High-power output: It supports 12kW three-phase AC, 11kW single-phase AC, and 10kW split-phase AC continuous output, covering RV air conditioners, high-power kitchen appliances, power tools, and other demanding loads.
• Strong built-in capacity: The main unit has a 7680Wh LiFePO₄ battery, suitable as the primary RV power system.
• Large expansion capability: Each extra battery pack has an 11776Wh LiFePO₄ battery. Up to 31 extra battery packs can be stacked, expanding total capacity up to 372kWh.
• Parallel stacking for higher output: The main unit supports stacked parallel connection without an additional parallel kit. Stacking can provide up to 24kW continuous output.
• Multiple charging methods: It supports utility power, high-voltage solar, low-voltage solar, EV charger, vehicle charging, generator charging, and wind power. The system can be fully charged in as fast as 70 minutes.
• UPS capability: It supports utility-to-battery switching within 10ms, allowing it to serve as an uninterrupted power source.
• Easy mobility and monitoring: The four-wheel chassis, large-diameter rollers, and APP-based monitoring make it easier to move and manage.

Typical RV Power Use

In an RV scenario, EP12000 can work as the main power center:

1. Charging during driving or parking
   Recharge through vehicle charging, solar panels, campsite utility power, or a generator.

2. Quiet night-time power
   Use battery power for the refrigerator, lighting, router, air conditioner, and essential living devices without generator noise.

3. Centralized high-load management
   Cooking, cooling, tools, and other high-power use can be powered from EP12000, reducing stress on the RV’s original electrical system.

4. Future expansion
   If the customer later adds more air-conditioning, freezer, tools, or EV emergency charging needs, extra battery packs and stacked parallel operation can expand the system.

Best-Fit Users

EP12000 is ideal for:

• Long-distance RV travelers
• Users who need air conditioning, kitchen appliances, tools, and network equipment at the same time
• Customers who want one system for RV living, outdoor work, home backup, and emergency EV charging
• Users who require future expandability

3. Recommended Solution 2: Lightweight RV + Network Backup — EP3600 as a Cost-Effective Main Unit

If the customer’s RV power demand is mainly lighting, refrigerator, router, laptop, small kitchen appliances, and short-time air conditioner use, and the five-room network system does not require high power, EP3600 is a lighter and more cost-effective choice.

EP3600 Application Advantages

According to the product documents, EP3600 provides up to 3.6kW continuous output and has a built-in 3430Wh LiFePO₄ battery. It can power high-power household appliances such as washing machines, microwaves, air conditioners, and various power tools, and can also provide emergency charging for electric vehicles.

EP3600 also supports stacked battery expansion up to 109kWh. The main unit supports stacked parallel operation, which can increase continuous output to 7.2kW. It also supports utility-to-battery switchover within 10ms, allowing it to work as a UPS.

Why EP3600 Works Well for a Five-Room Network

A five-room network system usually consists of low-to-medium-power loads that require stable and continuous operation. With its 3430Wh battery capacity, EP3600 can usually provide much longer runtime than a conventional small UPS for routers, switches, access points, cameras, and small NAS devices. Its 10ms switchover helps reduce the risk of network dropouts during power outages.

Recommended Connection Method

A practical setup can be arranged as follows:

• Connect EP3600 to utility power as the front-end power source for the network system.
• Connect the main router, switch, PoE switch, NAS, and surveillance host to EP3600.
• Distribute power and connectivity to access points or cameras in the five rooms through the switch.
• When utility power is normal, EP3600 maintains the battery and powers the devices.
• When utility power fails, EP3600 switches to battery output within 10ms to keep the network running.

Best-Fit Users

EP3600 is suitable for:

• Light-to-medium RV users
• Customers who need long-duration backup power for small networks, surveillance, and communication systems
• Users who do not need more than 10kW continuous output but want more capacity than a traditional UPS
• Budget-sensitive customers who still want expandability

Core value: Critical communication and network loads are isolated from high-power living loads, improving system reliability.

5. Why a Fuel Generator Alone Is Not the Best Choice

Fuel generators are common in RV use, but for this customer, they are better used as a charging source rather than the main all-day power supply.

Key reasons include:

1. Noise: At campsites or during night use, generator noise affects comfort and nearby users.
2. Emissions: Long-term operation is not suitable in enclosed or semi-enclosed environments.
3. Low efficiency for small loads: Running a generator only for routers, switches, and cameras is inefficient.
4. Network devices need stable power: Small network systems are better powered by a battery system with UPS capability.
5. Maintenance: Fuel generators require refueling, oil checks, and regular maintenance.

A better approach is to use the fuel generator only as an emergency charging source, while EP12000 or EP3600 provides quiet, stable, and controllable power output during normal use.

6. Implementation Advice: Calculate Loads Before Final Selection

Before confirming the final configuration, the customer should list all devices and divide them into three groups.

6.1 Always-On Critical Loads

These include routers, switches, APs, cameras, NAS, security hosts, and refrigerators. These devices should be connected to the UPS-backed circuit first.

6.2 Intermittent High-Power Loads

These include induction cookers, microwaves, coffee machines, kettles, and power tools. They have higher power demand but do not need to run all day, so they can be used in time-separated cycles.

6.3 High-Startup Loads

These include air conditioners, water pumps, and compressor-based equipment. Selection should consider not only running power but also startup surge demand.

If the customer mainly needs heavy-duty RV power and long off-grid operation, EP12000 is the better starting point. If the main need is lightweight RV use and network backup, EP3600 offers stronger cost performance. Extra battery packs can then be added according to real runtime needs.

7. Final Recommendation

For this RV enthusiast, if the goal is to use one system for both RV travel and backup power for a five-room small network, the recommended priority is:

1. Best overall solution: EP12000 main unit + extra battery packs
   Suitable for heavy-duty RV use, long off-grid runtime, and simultaneous power for air conditioning, kitchen appliances, tools, and network systems. Its 12kW-level output, 7680Wh built-in capacity, expansion up to 372kWh, and 10ms UPS switchover make it suitable for a complete RV + network backup scenario.
