The wall-mounted inverter is installed in the system cabinet and tightly integrated with other key components such as the energy storage battery, which significantly reduces the system installation time and cost and improves the stability and compatibility of the system as a whole, making it easy for installation, commissioning and maintenance.
It can realize automatic switching of working modes, such as automatically switching to off-grid power supply mode during grid outage, and also intelligently optimize charging and discharging strategies according to peak and valley tariff hours and users' power consumption habits, so as to reduce the cost of power consumption.
It supports self-generation and self-consumption, grid-connected power generation, off-grid power generation, peak and valley tariff optimization and other operation modes, which can be flexibly selected by users according to their own needs and local tariff policies.
Compatible with different brands and types of PV modules and energy storage batteries, as well as lead-acid batteries and lithium batteries, meeting the needs of different types of users.
According to the actual demand for electricity, the system configuration can be flexibly selected with different capacity and power, and has good expandability, which is convenient for users to upgrade and expand the system at a later stage.
Equipped with EMS energy management system, users can use cell phones or computers to remotely monitor and manage the system's operation status, and view real-time information on power generation, power consumption, battery power, etc. via Wi-Fi/Ethernet/GPRS/RS485 communication modes.

Capacity depends on your daily electricity consumption, number of rooms, and appliances. For a typical 3-bedroom home, 10–15 kWh is usually sufficient, while larger villas or farms may require 30 kWh or more.
| Home Type | Daily Consumption (kWh) | Recommended Battery Capacity | Recommended Inverter Power |
|---|---|---|---|
| Small Apartment | 8 – 12 | 5 – 10 kWh | 3 – 5 kW |
| Medium Home | 12 – 20 | 10 – 15 kWh | 5 – 8 kW |
| Villa | 20 – 35 | 15 – 30 kWh | 8 – 12 kW |
| Farm / Rural Home | 25 – 60 | 30 – 60 kWh | 10 – 15 kW |
For basic backup like lighting and refrigeration, a 5–10 kWh battery can provide 6–12 hours of power. Whole-home backup with HVAC and appliances typically requires 15–30 kWh capacity.
Yes. Modular battery systems allow starting with 5 kWh and expanding to 30 kWh or more as your energy needs grow.
A setup with 30–60 kWh battery capacity, 10–15 kW inverter, and 10–20 kW solar array reliably powers farm equipment, irrigation pumps, and household loads.
| Appliance | Power (W) | Daily Usage (h) | Daily Energy (kWh) |
|---|---|---|---|
| Refrigerator | 150 | 24 | 3.6 |
| Air Conditioner | 1500 | 6 | 9.0 |
| Washer/Dryer | 2000 | 1.5 | 3.0 |
| LED Lighting | 300 | 6 | 1.8 |
| TV + Router | 200 | 5 | 1.0 |
In sunny regions, smaller capacities (5–10 kWh) may suffice, while cloudier or colder areas should consider larger capacities (15–30 kWh) for reliable power.
A hybrid system with 5–15 kW solar, 5–10 kW inverter, and 10–20 kWh storage maximizes solar use and provides backup during outages.
Yes, with battery capacities above 30 kWh and proper load management, fully off-grid homes are achievable.
DoD indicates how much battery capacity can be safely used. LFP batteries support ≥90% DoD, improving usable capacity and battery life.
