5+5 kW of PV input across a 90-450 V MPPT window
Two solar inputs rated 5 kW each carry 20+20 A of current up to a 500 V maximum PV voltage, with tracking that starts at 100 V.

InvertersModel IVEM8048-II
An 8 kW single-phase off-grid inverter that pairs 5+5 kW of PV input with a 150 A charge ceiling, so the IVEM8048-II fills a 48 V bank as hard from the AC input as it does from the array.

Two solar inputs rated 5 kW each carry 20+20 A of current up to a 500 V maximum PV voltage, with tracking that starts at 100 V.
A 42-63 V battery window refills at the same 150 A ceiling whether the energy arrives from the array or from the AC input.
A pure sine wave at 50/60 Hz, regulated to within 5%, with the IVEM8048-II surging to twice its rated output for 5 s.
The IVEM8048-II rides an input as low as 90 V and as high as 280 V, disconnects at 90 V and hands its 8 kW of load to the battery in 50 ms.
AGM, Flooded, Li-Ion and Self-Defined banks charge at up to 150 A, 56.4 V boost and 54 V float, with RS485 to the BMS, an LCD and built-in WiFi.
A high-frequency, IP21 chassis on intelligent air cooling for -10 to 50 °C service, certified to IEC 62109-1, IEC 62109-2 and IEC 63027.
The Felicity Solar IVEM8048-II is an 8 kW single-phase off-grid inverter. It takes 5+5 kW of solar across a 90-450 V MPPT range, charges a 48 V bank at up to 150 A from the array or the AC input, and holds the load on a 230 V pure sine wave with a 50 ms transfer time. Charging headroom is the figure that defines this model: 150 A maximum charge current, matched by 150 A maximum AC charge current, into a 42-63 V battery window. The single tracker starts at 100 V, works to 450 V and tolerates 500 V maximum PV voltage on 20+20 A of input current. Boost charging holds 56.4 V, float settles at 54 V for AGM, Flooded, Li-Ion and Self-Defined banks, and RS485 carries the BMS link beside an LCD and built-in WiFi. Surge is twice the rated output for 5 s, regulation stays within 5%, and 6 units run in parallel. The high-frequency chassis is 23.7 kg net and 25.6 kg gross in a 712 x 582 x 259 mm carton, certified to IEC 62109-1, IEC 62109-2 and IEC 63027. Warranty is 2 Years.

150 A is the maximum charge current, and the maximum AC charge current is 150 A as well, so a 48 V nominal bank on a 42-63 V window fills at the same ceiling from an AC source as it does from the array. Boost charging holds 56.4 V and float settles at 54 V.
1 battery input accepts AGM, Flooded, Li-Ion and Self-Defined banks at 48 V nominal, talking to the BMS over RS485, and up to 6 IVEM8048-II units can be run in parallel. An LCD and built-in WiFi report the state of the system.
2 Years. The IVEM8048-II is certified to IEC 62109-1, IEC 62109-2 and IEC 63027, rated IP21, and carries overload protection, over temperature protection and short circuit protection, with intelligent air cooling for service from -10 to 50 °C. We are the authorised Felicity Solar distributor.
