EnPhase are piloting their new enPhase AC batteries from December in Australia . This ‘smart solar battery’ system is a major step towards intelligent solar storage.
The wall-mountable Enphase AC Battery is just 390 x 325 x 220 mm and weighs just 25 kg. Each battery includes a bidirectional micro-inverter to give 1.2 kW hours of energy and 275W/500W power output. Its ambient temperature range covers -20°C to 45°C and a limited warranty (> 80% capacity) for up to 10 years or 7300 cycles.
Enphase Energy’s Asia-Pacific managing director, Nathan Dunn says “We’ve partnered with ELIIY Power, a Japanese battery provider to develop a battery based on Lithium Iron Phosphate chemistry,” said Dunn. “This is an incredibly safe technology with a prismatic cell format that is very resilient to high temperatures and trauma events.”
There’s three simple steps to deploying the system:
1. Install the Networking Hub
Enphase Envoy-S Metered is an iPad sized monitoring system with the MyEnlighten app allows you to monitor solar power and mains power usage and generation. This enables you to figure out how many storage batteries you will need.
2. Add Storage Batteries
Install 2-3 Enphase AC Batteries to start creating sufficient battery reserve for your household needs.
3. Auto-Optimise
The system will then auto-optimise your power availability
Shifting energy to batteries when you’re generating more power than you use, an
Drawing electricity back from the batteries during peak usage periods.
You can then start mixing things up – change your habits, or add more batteries and solar panels – to find ways to further reduce your electricity bill.
