Felicity Solar IVEM4024-II 4kW Single-Phase Off-Grid Solar Inverter features

  • 60-500 V MPPT window, 60 V start-up

    The single MPPT tracker wakes at a 60 V start-up voltage and tracks to the 500 V maximum PV voltage, so a long string and a short one both work.

  • 27 A and 6 kW of PV input

    Maximum PV input current is 27 A and maximum PV input power is 6 kW, giving the 4 kVA inverter room to oversize its array.

  • 120 A charging, 28.2 V boost and 27 V float

    Charging reaches 120 A from solar or from AC into a 21-31.5 V bank at 24 V nominal, held at 28.2 V boost and 27 V float.

  • 4 kVA pure sine wave, 30 A output

    Rated apparent power is 4 kVA with 4 kW backup, delivered as a pure sine wave at 230 V single phase, 50/60 Hz, up to 30 A and 2x rated for 5 s.

  • 50 ms transfer over a 90-280 V input

    Transfer time is 50 ms and the AC input holds from 90 to 280 V, with 5% voltage regulation, 30 A maximum inverter/rectifier current and overload, over-temperature and short-circuit protection.

  • 10.4 kg net, 507 x 387 x 197 mm package

    Net weight is 10.4 kg and gross weight 11.9 kg in a 507 x 387 x 197 mm package, with an IP21 rating, LCD, built-in WiFi and RS485 BMS communication.

About the Felicity Solar IVEM4024-II 4kW Single-Phase Off-Grid Solar Inverter

The Felicity Solar IVEM4024-II is a 4 kVA single-phase off-grid solar inverter for a 24 V battery bank. One MPPT tracker works from a 60 V start-up across a 60-500 V window, accepting 27 A and 6 kW of PV, while charging reaches 120 A from either solar or AC. Output is a pure sine wave at 230 V, 50/60 Hz, regulated to 5% and capped at 30 A, with a surge rating of 2x rated for 5 s and a 50 ms transfer when the 90-280 V AC input falls away. The three-stage charger holds 28.2 V boost and 27 V float across a 21-31.5 V battery window, drives AGM, Flooded, Li-Ion and Self-Defined chemistries through one battery input, and talks to the BMS over RS485. Maximum efficiency is 93%, with line mode listed at >93%. The high-frequency chassis weighs 10.4 kg net and 11.9 kg gross, ships in a 507 x 387 x 197 mm package, carries an LCD and built-in WiFi, and is rated IP21 for -10 to 50 °C. It is certified to IEC 62109-1 and IEC 62109-2. We are the authorised Felicity Solar distributor and supply it with a 2 Years warranty.

Frequently Asked Questions

What PV array does the IVEM4024-II accept?

60-500 V is the MPPT working window, opened by a 60 V start-up voltage and closed by the 500 V maximum PV voltage. The single tracker takes up to 27 A of PV input current and 6 kW of PV input power.

How does the IVEM4024-II charge a 24 V battery bank?

120 A is the maximum charging current, available from solar or from AC. The charger holds 28.2 V boost and 27 V float across a 21-31.5 V bank at 24 V nominal, supports AGM, Flooded, Li-Ion and Self-Defined batteries through one battery input, and reaches the BMS over RS485.

What does the IVEM4024-II weigh, and what is its IP rating?

10.4 kg net and 11.9 kg gross, in a 507 x 387 x 197 mm package. The chassis is rated IP21 with intelligent air cooling, operates from -10 to 50 °C and stores from -15 to 60 °C, so it belongs indoors in a ventilated space.

What does the IVEM4024-II deliver on the output side?

4 kVA rated apparent power and 4 kW backup power, as a pure sine wave at 230 V single phase, 50/60 Hz, regulated to 5% and capped at 30 A. Surge is 2x rated for 5 s, transfer takes 50 ms when the 90-280 V AC input drops, maximum efficiency is 93%, and this model is not parallel capable.
