The Keysight E4360A Modular Solar Array Simulator is a dual-output programmable DC power source that simulates the output characteristics of a solar array. It is primarily a current source with very low output capacitance, capable of quickly reproducing the I-V curve of different arrays under different conditions such as temperature and age. A single 2U-high mainframe provides up to 2 outputs and up to 1200 W, and the platform is available either as an off-the-shelf instrument or integrated into a full turn-key solar array simulator system.

Solar array simulators are used in satellite test applications, where solar panels with unique I-V characteristics power the satellite and a specialized supply is needed to verify the satellite power system and the design of the power bus regulator on the ground. They are also used in residential photovoltaic test applications: a solar array simulator verifies that a microinverter tracks the maximum power point under varying environmental conditions such as sunny, cloudy, shadowing, and different temperatures, and confirms that the microinverter is reliable and efficient.

ValueTronics stocks and holds its own inventory in a 20,000 sq ft secure warehouse at 1675 Cambridge Drive in Elgin, Illinois. Every pre-owned unit is inspected and functionally verified in-house by our technicians before it ships, while new units ship factory-sealed exactly as received from the manufacturer.

Brand Heritage

The instrument's manufacturer traces its corporate lineage from Hewlett-Packard to Agilent Technologies, which was spun out in 1999, and then to Keysight Technologies in 2014. The brand has been evolving since 1939.

Compare Other Models in This Series

The E4360 is a modular platform built around the E4360A mainframe, which holds up to two solar array simulator modules in 2U of rack space and delivers up to 1200 W total. Buyers can order the mainframe and modules separately for self-assembly, or order a preconfigured, fully assembled mainframe shipped as a tested instrument.

Two simulator DC modules are offered: the E4361A and the E4362A, along with J-option variants of those modules. Preconfigured units pair an E4360A mainframe with two like modules, with the E4367A using two E4361A modules and the E4368A using two E4362A modules.

Each model linked below is its own dedicated product page with pre-owned condition-matched pricing. Select the configuration that matches your required output ratings and ordering options.

The modules differ in their output ratings as shown in the comparison table. The E4361A module is rated 65 V, 8.5 A, 510 W, while the E4362A module is rated 130 V, 5 A, 600 W; J-option variants such as the E4362A-J01 through -J05 and E4361A-J01 carry their own voltage, current, and power ratings. Across all modules the recommended calibration interval is 1 year and output terminal isolation is ±240 Vdc from chassis ground.

Preconfigured mainframes consolidate the choice: the E4367A is an E4360A mainframe with two E4361A modules and the E4368A is an E4360A mainframe with two E4362A modules, while the E4366A ships with two special-option modules. Refer to the comparison table for the per-model output power, voltage, and current ratings that distinguish each configuration.

Additional differences in specifications beyond the few shown above are not listed here — see each model's full specifications below.

Product Core & Specifications

Important: Maximum output power is limited to 600 W at 100/120 Vac; full 1200 W output requires Option 904 and operation at 220/240 Vac.

Important: When configuring a mainframe with fewer than 2 filled module slots, you MUST order a Filler Panel Kit (Option FLR or E4369A) to fill any empty module slot for proper operation; each kit contains one filler panel.

Important: For rack mounting, you MUST order the Rack Mount Kit (Option 908); standard rack mount hardware will not work.

Important: The mainframe has side air vents; 1U of space is required between the instruments to retain proper cooling.

Important: The unit may go out of specification when subjected to RF fields of 3 volts/meter in the frequency range of 26 MHz to 1 GHz.

Important: Electrostatic discharges greater than 1 kV near the I/O connectors may cause the unit to reset and require operator intervention.

Important: A power cord (line cord) option must be selected and ordered separately; it is not included by default with the mainframe.
