Every MountRex unit has a built-in BMS with complete protection and monitoring. It manages cell voltage, current, temperature and state-of-charge in real time — and communicates all data to your inverter via CAN or RS485.
Most distributors in Pakistan sell whatever brand is available. MountRex is Charania Renewables’ own label — specified by our engineers, supplied by Zetara and warranted directly by us.
When you buy a MountRex, your warranty claim comes to us. We manage it. If there is a fault, we resolve it. No overseas referral, no waiting.
The specification is fixed and controlled. The unit you receive today matches what we sized your system for. We do not substitute modules between orders.
