IDEEI QB82-48 (8.2kW) and QB102-48 (10.2kW) dual-PV hybrid solar inverters share a 48V battery system with pure sine-wave 220-240V output and 160A solar charging, for use with or without batteries.
The QB82-48 and QB102-48 provide 8.2kW and 10.2kW of hybrid pure sine-wave power with dual photovoltaic inputs and a 48V battery system for both models, running with or without a battery bank. The published data sheet confirms the electrical values in the model table; load surge and battery communication still require project review.
Each model carries two independent PV inputs of 5,400W each, with a 90–450V DC MPPT range, 120V DC start voltage and 2 × 18A maximum PV input current. Two strings — for example east and west roofs — can each work at their own optimum instead of sharing one tracker.
Both models use a 48V DC battery system: the QB82-48 delivers 8.2kW / 8.2kVA at 35.6A nominal output current, the QB102-48 delivers 10.2kW / 10.2kVA at 44.3A. This is the step up from the 24V/48V QB42/62 pair for larger homes, clinics and workshops with motor loads.
Maximum solar charge current is 160A and maximum AC charge current is 140A, at 94% DC-to-AC efficiency. Check the surge behaviour of the largest motor against the model’s rated output before ordering, not just the sum of nameplate watts.
Both models run with or without a battery bank. Off-grid mode is the default and grid-tie hybrid mode is LCD-selectable, feeding excess solar to the grid; communication options are RS232 / RS485 / Wi-Fi / GPRS with lithium-battery support.
The table separates verified published data from project-dependent choices. Match the product by electrical ratings and application conditions; do not select from the headline power value alone.

A dependable quotation requires the complete operating profile, not only the nominal power. IDEEI reviews voltage, current, source or motor data, duty, environment, required options and destination together so the final configuration, accessories, protection devices and commercial scope can be stated clearly.
Separate continuous load from startup surge loads such as pumps, compressors and motors. Check the PV string at the lowest expected temperature so open-circuit voltage remains below the product limit. Where a battery is used, match chemistry, nominal voltage, charge current and communication protocol. Source priority, transfer behavior, neutral arrangement and generator compatibility must be confirmed for the complete system.
Installation and commissioning must be completed by qualified electrical personnel. Isolate all energy sources before wiring, verify terminal functions against the current manual, provide protective devices and grounding, and apply the published derating guidance for altitude, temperature, enclosure and cable length. Product-page data supports preliminary selection and does not replace project engineering or local code compliance.
Yes. The QB82-48 and QB102-48 run with or without a battery bank. Without batteries, daytime loads run from PV (and utility or generator where connected) as long as the available source can support the connected load; battery-free operation provides no night-time backup. Confirm the intended operating mode before wiring.
Use the selected model’s permitted PV voltage window and maximum open-circuit voltage. Check cold-weather Voc, operating Vmp, current, total array power and local irradiance rather than selecting from inverter kW alone.
Supported AC input and source-priority modes depend on the selected series. The transfer arrangement, protection devices and neutral/earthing scheme must be confirmed for the installation.
Communication is model- and project-dependent. Confirm Wi-Fi, GPRS, RS232, RS485 and the required lithium-battery protocol before ordering.
