Features

  • All-in-one architecture integrates battery, inverter and management. The 15.36kWh combines storage, a hybrid inverter and MPPT in one enclosure, cutting installer time and wiring.
  • Built-in inverter and MPPT handle solar, grid and backup. It harvests PV, powers loads and switches to battery backup within moments of an outage, with no manual action.
  • Intelligent EMS optimizes self-consumption and savings. The system routes power between solar, battery, grid and load in real time, enabling time-of-use scheduling and peak shaving.
  • Real-time monitoring keeps status visible. Through the unit display communication you can check state-of-charge, power flow and faults on site or remotely.
  • Safe LiFePO4 chemistry with multi-layer protection. Inherently stable cells plus system safeguards monitor over-voltage, over-current and temperature during daily operation.
  • Scalable storage expands as demand grows. Add battery modules or parallel units to increase capacity, protecting your initial investment as needs rise.

Applications

  • Priority-Load Backup: Segment load management keeps fridge, Wi-Fi, and lights on first, shedding non-essentials during outages.
  • Grid-Connected Solar Self-Consumption: Stores midday PV and can feed surplus to the grid at PF >0.99.
  • Whole-Home Essentials: Supplies up to 6200W of pure-sine-wave 230Vac for daily appliances.
  • Off-Peak & Peak Shaving: Charges from the grid off-peak and discharges in the evening to lower bills.
  • Remote Monitoring: RS232, WiFi, and GPRS links let owners check status from anywhere.
  • Capacity Step-Up: The 5.12–20.48kWh model range matches rising household energy needs.

Energy Management & System Architecture

The SW-THEP-10LV3 manages energy as a single-phase all-in-one: a 120A MPPT, pure-sine-wave inverter, and 51.2Vdc LiFePO4 battery (300Ah, 16S1P×3) share one cabinet. PV generation enters the MPPT, which accepts up to 6500W across a 60–500Vdc range (90Vdc start-up) and converts it to charge the pack or feed the load. Segment load management splits priority main loads from a secondary battery-mode circuit, directing stored energy where it matters most.

Battery storage delivers up to 6200W through the inverter/PCS at a 98% peak conversion efficiency, with 94% DC-to-AC in battery mode. Intelligent control manages charging from PV or the grid (up to 120A solar, 100A AC) and load priority via selectable input ranges, while RS232, WiFi, and GPRS links report status and support remote monitoring.

Grid, Backup & System Integration

The system works as a grid-connected ESS, supplying 220/230/240Vac with feed-in support at PF >0.99 and a fast 10000W surge for motor loads. Solar self-consumption is built in: daytime PV powers the home and charges the battery first, then surplus can follow the grid path, cutting utility purchases.

Backup comes from segment load management—priority main loads (up to 6200W) stay on first, with a secondary 2067W battery-mode circuit for essentials during outages. The 51.2Vdc LiFePO4 bank recharges from PV or the grid, and the family's 5.12–20.48kWh range lets households step up capacity as demand grows.

Warranty

LiFePO4 batteries for 5 years, hybrid inverters for 2 years, and solar panels under the supplier policy of a 10-year product warranty plus 30-year linear power warranty. If you experience any quality issues within the applicable warranty period, please contact us and we will arrange a replacement or repair promptly.

Frequently Asked Questions

Will it connect to my home grid and solar panels?

Yes. It connects to a 220/230/240Vac single-phase grid with feed-in support (PF >0.99) and takes up to 6500W of PV across a 60–500Vdc MPPT range via MC4. Confirm local grid-tie rules before export.

How long can it power my home during an outage?

With 15.36kWh of LiFePO4 and 6200W output, it covers essential loads—lighting, Wi-Fi, a fridge—for hours by load; a 10000W surge starts motor devices.

What happens to my important loads during a blackout?

Its segment load management keeps priority main loads (up to 6200W) on first and shifts a secondary 2067W battery-mode circuit, so fridge and routers stay up while less critical loads shed during an outage.

Can I get more capacity as my needs grow?

The THEP family spans 5.12–20.48kWh in fixed steps, so you can select a higher-capacity model as household demand rises.
