  • 90–520 V battery voltage range and dual MPPTs for versatile system design
  • Auxiliary generator input extends off-grid autonomy during prolonged outages
  • Compact enclosure rated for indoor or outdoor installation (IP65)
Technical & Grid Integration Specs
Grid + BatteryVDE-AR-N 4105, G98; high-voltage LFP battery stack compatibility (90–520 V)
EPS BackupATS switchover <20 ms; supports critical load panel and generator auto-start
CommunicationRS485 Modbus RTU, CAN bus BMS, Wi-Fi/4G dongle for cloud monitoring
Surge ProtectionType II AC/DC SPD, battery over-current protection, and RCMU monitoring

Use this model when…

  • The site requires a dedicated 3-6 kW single-phase hybrid with generator input
  • The string current matches module specs with zero clipping risks
  • The installer has confirmed the matching local grid-code certifications

Choose another model when…

  • The total string open-circuit voltage exceeds safety limits
  • A different grid phase or system-level battery topology is required
  • Local regulations demand centralized substation inverter architectures

Quote-prep checklist

  • Confirm battery stack voltage is within 90–520 V range and BMS protocol matches
  • Verify generator auto-start signal wiring and cooldown timer configuration
  • Specify EPS backup load list and confirm panel amperage rating

Where This Model Fits Best

Three application scenarios for the H2-3k~6k Single Phase Hybrid Inverter, showing where this 3-6 kW product belongs on the shortlist and where it does not. Review these before quote approval.

H2 urban home application
01

Residential Self-Consumption System

For a 3-6 kW single-phase home PV installation with battery storage for self-consumption, the H2 3-6kW provides the power class and battery compatibility needed. Confirm daily energy consumption, battery capacity, and backup-load requirements before sizing.

  • Daily energy consumption profile assessed
  • Battery capacity and voltage range confirmed
  • Backup-load circuit identified

An undersized battery will limit self-consumption. Size the battery to match daily consumption patterns.

H2 suburban rooftop application
02

Backup-Ready Retrofit Installation

When upgrading an existing residential PV system to add battery backup, the H2 3-6kW provides hybrid conversion. The installer should review the quick installation guide and user manual for wiring, CT/meter placement, and commissioning steps.

  • Quick installation guide reviewed
  • CT and meter placement planned
  • Existing PV array compatible with H2 DC input

Backup wiring must be done by a qualified electrician. Incorrect CT placement causes commissioning failures.

H2 restricted grid application
03

Installer Standard Residential SKU

For solar installers stocking a standard single-phase hybrid inverter for residential projects, the H2 3-6kW (3-6 kW) covers the most common home PV scale. Review the datasheet, quick guide, and configuration instructions before committing to volume orders.

  • Datasheet and quick guide reviewed
  • Battery partner list confirmed
  • Volume terms confirmed with Sunriver quotation

Confirm warranty terms and after-sales support process before volume procurement.

FAQ for Technical Review

Product-specific technical questions for buyers, installers, and distributors reviewing the H2-3k~6k Single Phase Hybrid Inverter before quotation. Each answer includes technical criteria, a pre-quote checklist, and a caveat to avoid common procurement mistakes.

How do I confirm the H2 3-6kW is the right single-phase hybrid inverter?

Confirm your AC output target is within 3-6 kW, single-phase grid connection, and PV input within 4.5 – 9 kW DC (150 %) DC. This is SAJ's current-generation single-phase hybrid inverter for residential self-consumption and backup-ready systems. If you need three-phase output, review the H2 5-10kW three-phase model.

What to check

  • Confirm AC output target within 3-6 kW
  • Confirm single-phase grid connection
  • Confirm PV input within 4.5 – 9 kW DC (150 %) DC
  • Confirm battery voltage range and compatibility

If you need three-phase output or higher power, step up to the H2 5-10kW three-phase model.

What battery setup works with the H2 3-6kW?

The H2 3-6kW works with external LiFePO4 batteries. Confirm the battery voltage range, charge/discharge current, and BMS communication protocol before quoting. The configuration instructions provide guidance on system setup and battery integration.

What to check

  • Battery voltage range confirmed
  • Battery type (LiFePO4) and BMS compatibility checked
  • Configuration instructions reviewed
  • Battery charge/discharge settings confirmed

Do not assume a battery is compatible without verification. Share battery specifications with Sunriver if uncertain.

What documents are essential before quoting the H2 3-6kW?

Review the quick installation guide for physical installation requirements, the user manual for commissioning and monitoring, and the configuration instructions for battery and system setup. Having all three documents reviewed before quoting reduces clarification loops.

What to check

  • Review quick installation guide for mounting and wiring
  • Review user manual for commissioning and monitoring
  • Review configuration instructions for battery setup
  • Confirm grid-code compliance for destination country

Having all three documents reviewed before quoting prevents post-purchase configuration issues.

What backup-load planning is needed for the H2 3-6kW?

The H2 3-6kW provides backup power up to 3-6 kW — confirm which circuits will be on the backup panel and that the total backup load is within the inverter capacity. The installer should review the user manual for backup wiring and CT/meter placement requirements.

What to check

  • Identify backup-load circuits
  • Confirm total backup load within inverter capacity
  • Review user manual for backup wiring instructions
  • Plan CT and meter placement

Backup capacity is limited to the inverter rated output. Do not overload the backup circuit.

What project information speeds up the H2 3-6kW quote?

Send the destination country, AC output target, PV array size, battery specifications, and backup-load requirements. If remote monitoring is required, specify Wi-Fi or LAN preference. Include whether CT and meter are included in the order or sourced separately.

What to check

  • Destination country and grid code
  • AC output target and PV array size
  • Battery specifications
  • Backup-load requirements and monitoring preference

Quote turnaround depends on complete project data. Incomplete data adds clarification loops.
