The modular rack-mounted inverter design integrates PV inverter, energy storage, charging and discharging, and intelligent power distribution, which is easy to install, saves space, and meets the needs of diversified scenarios.
Equipped with EMS energy management system, it can dynamically regulate energy distribution, prioritize the use of PV power generation, and store or grid-connect the remaining power; combined with the peak and valley tariff strategy, it can automatically select charging in low-priced hours and discharging in high-priced hours, thus lowering the expenditure on electricity.
With three core modes: self-generation and self-consumption, grid-connected power generation, and off-grid standby, it supports rapid switching to off-grid power supply in case of power outage, and guarantees continuous operation of critical loads.
Built-in BMS, intelligent battery temperature control and multiple protection mechanisms (overcharge/overdischarge/short-circuit protection), adapting to high temperatures, humidity and other complex environments, to ensure long-life and stable operation of the system.
Supports flexible expansion of energy storage battery capacity, suitable for different scales of electricity consumption; compatible with mainstream PV modules and grid standards to meet future upgrade requirements.

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.
