OUR CAPABILITIES
The right products,
with installation and operational support.
We design systems for each site and supply products. We support installation and commissioning, and build interfaces for equipment status and maintenance work.
Systems matched to each site
We review electricity use and installation conditions, size the system, and select the solar PV, inverter and ESS combination and installation approach.
Product supply & support
We supply POEN batteries and check voltage and communication compatibility with inverters. We support selection, installation and commissioning, with technical support after supply.
BESS technical cooperation
We joined the Long Hậu 261 kWh commercial BESS project as a specialist partner, supporting system configuration, installation management, commissioning and operations.
Data and service workflows
We build interfaces for operators and owners to review equipment status and maintenance history. We also develop FEMS for factory power analysis and equipment and document management.
RESIDENTIAL SOLAR PV & ESS
Energy for your home,
designed around daily life.
We configure solar PV and ESS around a home's electricity use and installation conditions. We directly handle installation, commissioning and user guidance.

Site survey & configuration
We review electricity use and bills, inspect the roof and electrical equipment, and check space for batteries. System capacity and product combinations follow the loads to be supplied.
Installation & commissioning
We install and configure products, check system operation during commissioning, and explain how to use the system.
User guidance & technical support
We answer questions about use and settings after installation, and provide a technical support contact for inspection needs.

- Technical support
- We advise on product configuration, check installation and settings, and provide technical support for on-site commissioning.
INDUSTRIAL SOLAR PV & ESS SUPPLY
Energy solutions,
starting on the factory roof.
We supply integrated solar modules, inverters and ESS for factories and commercial facilities. We review configurations for each site and provide installation and commissioning support.
- 1Solar panels
Convert sunlight into direct-current (DC) electricity.
- 2Solar inverter
Converts DC to alternating current (AC) and feeds the switchboard.
- 3Battery system (ESS)
Connects to the switchboard to store and supply electricity.
- CONNECTIONS
Solar panels → Inverter → Switchboard → Factory loads
ESS ↔ Switchboard
Industrial solar PV
We review the roof condition and electricity use pattern, then select solar modules and inverters for the installation environment.
Integrated product & system supply
We check compatibility across modules, inverters and ESS before supply, and provide technical support for installation, configuration and commissioning.
Solar PV & ESS integration
We review solar-only and solar-plus-ESS configurations, selecting an integration approach around electricity use times and installation conditions.
INDUSTRIAL ESS SOLUTIONS
Store electricity,
use it when needed.
We review electricity use and time-of-use tariffs to size ESS energy and power capacity and charging/discharging conditions. Technical support spans configuration, installation management, commissioning and operations.
Long Hậu project participation
We participated as a specialist partner in a commercial BESS project at the expanded Long Hậu Industrial Park.
- Configuration & installation
- We reviewed the BESS configuration for the site and contributed to installation management and technical support.
- Commissioning & operations
- We supported commissioning and operational readiness after installation, and reviewed site-specific operating conditions.

CENTRALIZED O&M MONITORING
Multiple sites,
one place to check their status.
Monitor solar PV and ESS status and data reception in one place. Our O&M service manages inspection requests, staff actions and result reporting.
SITE EQUIPMENT
INFORMATION BY USER
Central overview
Compare equipment status and data reception across sites. Select a site to review its details.
Solar PV & ESS details
Review generation, electricity use and battery data. The last reception time shows when the data was received.
Service history & reports
Check the person responsible and progress of each inspection request. Record service history and share reviewed results in customer reports.
Operator & owner monitoring
Operator and owner portals,
a clear view of each site.
Operators review generation across sites, while owners view their own energy and battery data.
Operator portal · Overview
Compare site status and data reception to identify which sites to check first.
Operator portal · Site details
Review generation, electricity consumption and grid import trends for the selected site.
Owner portal · Battery monitoring
Owners can check their electricity use, battery power and state of charge (SOC).
RESIDENTIAL MONITORING
Home energy and service,
in the palm of your hand.
A residential service for checking solar generation and battery status, submitting inspection requests and reviewing service results in one place.
Check generation, batteries
and equipment status.
View power flows between solar PV, batteries, your home and the grid. Check device status and alerts.
Track the progress
and results of your request.
Submit a service request and track the assigned staff member's progress. Review inspection results and follow up with further questions.
From service request to results

FACTORY POWER ANALYSIS
In development
Understand factory electricity use
across the day.
We are developing FEMS to analyze factory electricity use patterns, solar generation and self-consumption.
Power use patterns
Analyze electricity use by time of day and per unit of production. Check for electricity use while equipment is stopped.
Supply and consumption
Separate grid imports from on-site solar generation and self-consumption. Compare electricity supplied to the factory with its consumption.
Metering data quality
Identify missing, duplicate and estimated metering intervals. Review data reception to assess the data used for analysis and reporting.
FACTORY EQUIPMENT & DOCUMENTS
In development
Equipment, power data and records, managed together.
We are developing FEMS that links equipment and metering points to the factory layout, with related documents and review history.
Factory layout and equipment
Locate buildings and equipment on the layout. Select equipment to view linked metering points and documents.
Equipment-to-meter links
Review power data from metering points alongside linked equipment. Connect layout information with power analysis results.
Document review and revisions
Assign reviewers and deadlines, and record required revisions. Retain earlier document versions and review history when documents change.
Report evidence and history
Keep source documents, figures and review results with each report. Revisit past reports and the materials used to prepare them.
