The HERF-1200 is a micro-inverter from Estar Energy (Estar/HERF) designed for solar panels. It's a "4-in-1" micro-inverter, meaning it can connect four solar panels (or modules) across two MPPTs. It converts the direct current (DC) from the panels into alternating current (AC) to enable grid-tie connection.

Specifications

Feature Value / explanation
Warranty period 10 years (product warranty)
DC / Input (DC side) • Recommended panel power: approx. 240-420+ W modules per input
• MPPT voltage range (operating voltage): 16-48 V
• Starting voltage: 22 V
• Maximum DC voltage: 60 V
• Maximum DC current: 4 × 13 A (distributed over the inputs)
Number of MPPT / inputs 2 MPPTs, 4 DC inputs (so 2 ​​inputs per MPPT)
AC / Output (AC side) • Rated power AC: 1200 VA / 1200 W
• Nominal AC voltage: 230 V (common in NL/EU), with AC range 180-270 V
• Frequency range: 45-55 Hz around 50 Hz
• Maximum AC current: ~ 5.22 A (based on power at 230 V)
Efficiency & consumption • Maximum efficiency: approx. 96.5 %
• CEC peak efficiency ~ 99.5% (under certain conditions)
• Night consumption / standby consumption: < 0.05 W
Protection class & temperature range • IP67 – Dust and splash/water proof in outdoor conditions
• Working temperature: -40 °C to +65 °C
Mechanical / dimensions / weight • Dimensions: approx. 275 × 204.5 × 41.6 mm (width × height × depth)
• Weight: ~ 4.9 kg
• Cooling: natural convection (no fan)
Other functions / communication • Communication via 2.4 GHz wireless possible; optionally with a data logger (“DCU”) to manage monitoring, limits, etc.
• Power factor adjustable (cos φ) ≈ 0.8 (leading or trailing)
• Low harmonic distortion (THD <3%)

Plus points

  • Higher power per unit : The HERF-1200 delivers around 1.2 kW AC, which is relatively high for microinverters — meaning you need fewer units for a given total power.

  • Four solar panels per unit : makes installation more compact/cheaper compared to one inverter per panel, while still benefiting from module-level MPPT.

  • Robust protection (IP67) and wide temperature range ensures reliability in outdoor conditions.

  • Low starting voltage and wide MPPT range means it can deliver power even in less than ideal light conditions/cloud cover.

  • Low night-time consumption minimizes losses when PV panels are not producing power.

  • Flexible installation : modular operation, option to monitor performance via app/data logger.
