Where This Model Fits Best

Use these scenarios to decide whether this model belongs on the shortlist before quote approval.

Urban Homes with Frequent Power Cuts

Who it’s for: Residential homeowners in cities facing grid instability or load-shedding (e.g. Bangkok, Manila).

UPS-level transfer keeps lights, routers, and appliances running without blink
Battery bank ensures full night coverage (5–10 kWh typical)
Low noise & compact design ideal for bedroom-adjacent install

Success Tip: Combine with 5kW lithium battery + Wi-Fi dongle for seamless smart-home integration.

Suburban Rooftop Solar + Storage Projects

Who it’s for: Homes with rooftop PV aiming to boost solar self-consumption and bill savings.

Component	Recommended Spec
PV Array	4–6 kW
Battery Bank	7–10 kWh
Daily Savings	Up to 70%

This is the most popular setup for middle-income homes in Malaysia and Thailand where self-use is prioritized over grid feed-in.

Zero-Export Residences with Grid Restrictions

Who it’s for: Households in regions where grid authorities prohibit solar export (e.g. MEA Thailand, EVN Vietnam).

Enable zero-export mode via eSolar Portal
Configure feed-in limiter with external CT clamp
Track compliance in real-time via dashboard

Note: This feature ensures 100% grid compliance while still powering daytime loads with solar and storing surplus for night use.

FAQ for Technical Review

Use these questions to resolve monitoring, warranty, compatibility, and procurement concerns before approval.

How do I choose between H1, H2, and H2 LV?

Start with phase, battery path, and backup scope. H1 is usually the single-phase starting point, H2 covers higher-output hybrid paths, and H2 LV is the better fit when low-voltage battery architecture is part of the decision.

What battery and backup details should be confirmed before approval?

Confirm battery voltage path, backup expectation, and whether the project needs zero-export or time-of-use control. Those three points usually determine whether the shortlist is technically safe before the commercial quote moves forward.

When should I ask for meter, accessory, or compatibility review?

Ask before internal approval when the system needs export control, smart metering, monitoring accessories, or battery matching. Compatibility questions are much cheaper to solve before the buyer locks the model list.

Which file should I open first for a hybrid project?

Use the datasheet to confirm phase, PV range, battery path, and backup basics. Move into the user manual or quick guide when the installer needs detailed wiring, commissioning, or operating-mode review.

What should I include in the request if I need pricing or model guidance?

Send the project type, phase, battery requirement, destination market, and expected quantity. If the buyer is comparing multiple backup strategies, include the critical load expectation so the model recommendation stays aligned with the use case.
