RCTerra Class 1.0 233
A 233 kWh outdoor cabinet with liquid cooled RCT Power battery modules already installed, sized for sites that have outgrown an all in one unit.
Why sites choose the 233
Liquid cooled, factory installed
Five RCT Power battery packs of 46.592 kWh sit in a single rack, liquid cooled and preinstalled before the cabinet leaves the factory. Nothing about the thermal system is assembled on site.
Backup that switches in 50 ms
Automatic backup power switching within 50 milliseconds, with a black start function so the system can bring itself up without the grid present.
Solar can come in on the DC side
An optional DC/DC converter takes two MPPTs at up to 100 kW and better than 99 per cent peak efficiency, so PV can be stored without a round trip through an AC inverter.
Protection at every level
Flammable gas detection and exhaust, smoke and temperature detection, aerosol fire suppression, dry pipe and sprinkler, siren and strobe alarm, and an emergency stop button.

Not sure whether you need 233 or 261
The two cabinets look similar on paper. The difference shows up in cycle life, fire protection and how they behave on a hot afternoon. Send us your interval data and we will model both.
