VRLA solutions

Solar battery storage for telecom, businesses, agriculture and more. Scalable to up to 2.1 MWh. Proven, reliable, cost effective. High capacity solar storage.

Our VRLA Solution PES1 is designed for use with systems ranging from small scale multi kWp projects to solar power plants sized 2.1 MWh and can be used for a wide range of applications. From solar telecom towers (such as the broadcast tower in Muswellbrook, that we took off the grid in 2014) to small businesses, hotels, warehouses, agricultural operations and more.

PES 1 is a truly complete AC output fully integrated solar-battery storage system with excellent power characteristics that is reliable, flexible, scalable and suitable for a multitude of off-grid and on-grid applications, from remote communities to facilities with high power needs. Single and multiple containers can be integrated flexibly within a single SCADA controlled and supported energy system in the following configurations:

PES1 Possibilities
Nominal power AC 6 kW–300 kW
Maximum power 5 min 8 kW–390 kW
Energy storage capacity 100 kWh–2.1 MWh
Nominal PV Power DC 18 kWp–1 MWp
On-Grid AS 4777 compliant
Off-Grid AS 4509 compliant

The whole system is remote  monitored and controlled with a manned control room and technical support 24 hours a day. The system uses top quality maintenance free Valve Regulated Lead Acid sealed batteries combining extreme current capacity, long design life, deep cycling and inherent reliability and safety. Battery charging and AC power is delivered through tried and tested island and grid-tied inverters that supply high quality true sine wave, low THD power.

PES1 is delivered in special tempered insulated 20 foot containers, pre-configured and tested and ready to  install with minimum on-site works even in hard to reach locations.

PES1 is the conclusion of many years of development work and full scale reference deployment data to find an optimal solution using readily available tried and tested technologies in one integrated system. The system is built around our professional supervisory control and data acquisition SCADA controls which are highly reliable and use smart algorithms to optimise performance and extend battery life.
