AERL Products

Maximum power point tracking (MPPT) solar charge controllers for DC-coupled battery systems. The SRX is wall mounted; the SRX-R is the same charger as a module for 19-inch racks, two to a 2U shelf. A 600 V PV input lets long strings run from the array, and the array can be up to twice the controller's rating (130% at 24 V). On-board ground-fault detection, CAN, RS485 and USB; set up and updated with AERL Link. Australian engineered. The SRX 600/70-48 (48 V) is TÜV certified.

A 5.12 kWh lithium iron phosphate (LFP) battery module for 48 V systems, 19-inch rack-mount. It runs Managed, over CAN bus with Deye, Victron Energy, Selectronic SP PRO and Solis inverters, or Self-Managed with inverters and chargers programmed by hand. Up to 64 modules in parallel; pre-wired cabinets hold 4, 6 or 10 modules, indoors (IP20) or outdoors (IP55). Supplied and supported by AERL.

An 88.4 kWh LFP battery cabinet at 140.8 V nominal, IP55, for large off-grid systems. It runs with an AERL Nexus Gateway on its CAN bus and is designed for DC coupling with the CoolMax SRX 600/30-120 and the Selectronic SP PRO SPLC1200 and SPLC1202. Up to 16 cabinets in parallel (1.41 MWh); the Kakadu Combiner Box parallels up to 4. Supplied and supported by AERL.

Commercial energy storage systems in one outdoor cabinet: a Solinteg M2HT hybrid inverter, an LFP battery, BMS, fire protection and air conditioning. The All-In-One pairs five power ratings with four battery sizes; the All-In-One Max pairs 125 kW with 257 kWh. The All-In-One is for grid-connected and off-grid sites; the All-In-One Max is for off-grid sites (grid connection pending CEC listing). Both support generators and off-grid paralleling. Manufactured by Solinteg; supplied and supported by AERL.

Three-phase hybrid inverters for high-voltage LFP batteries, sold on their own for systems built around a battery from Solinteg's compatibility list. Manufactured by Solinteg; supplied and supported by AERL.

The gateway between site equipment and AERL Cloud: it finds supported devices on its CAN bus (CoolMax SRX, LiFe², Kakadu 120, Battery Sense) and polls Modbus devices such as the Selectronic SP PRO and the CoolPro Meter Board, for remote monitoring, alerts, configuration and firmware updates. It is also the EMS of a Kakadu 120 system. The Nexus 4G adds a cellular modem, digital inputs and output relays. Australian engineered and made in Australia.

A 10.1-inch sunlight-readable touch screen with an embedded computer in a full-metal housing, for a local view of the system at the switchboard: live inverter and generator values, faults and alarms.

A remote temperature and voltage sensor for battery banks without a BMS that reports them, typically lead-acid. It plugs into a CoolMax SRX's CAN port, which powers it, and gives the SRX the battery temperature and voltage for temperature-compensated charging and the low-temperature cutoff. Australian engineered and made in Australia.

Insulation monitoring devices for PV and battery systems: they detect insulation faults between DC conductors and earth, and alarm with a buzzer, LEDs and fail-safe relays. They support compliance with the earth-fault requirements of AS/NZS 5033 and AS/NZS 5139. The EG-600 monitors two circuits, the EG-600-SC one. Australian engineered and made in Australia.

An impressed current cathodic protection (ICCP) controller with a high-current DC-DC converter, for remote, solar-powered sites: pipelines, tanks and structures. Passive cooling, IP65 enclosure, parallel operation for large structures, and optional reference-cell potential control. The Surge Buster lightning protection module is required in lightning-prone applications (pipelines or structures longer than 100 m or higher than 10 m) and optional elsewhere. CoolPro: Australian engineered. Surge Buster: Australian engineered and made in Australia.
