7.1 15A MPPT Dual Battery Solar Charge Controller Replacement Service
7.1 15A MPPT Dual Battery Solar Charge Controller Replacement Service
Electrical System Inspection Update
CCCAMPERS has conducted a thorough inspection of your camper van's electrical system. Regrettably, it appears that your current MPPT Dual Battery Solar Charge Controller is not functioning as intended. We understand the importance of this component in ensuring the efficient charging of your auxiliary battery, and we are committed to resolving this issue promptly.
The Solution: Next-Generation MPPT Upgrade Service
To address this matter, we are pleased to offer a replacement dual-battery MPPT solar charge controller service. Our engineering team will ensure that your new controller is installed correctly, tested, and precisely calibrated to meet your camper van's custom requirements.
The second generation of this intelligent charge controller is engineered to extract the highest possible power from solar panel arrays up to 225W into a 12V or 24V battery system. By actively modifying and matching the voltage coming from your panels to suit your battery bank's real-time state of charge, it guarantees maximum delivery with minimum electrical loss, whatever the weather conditions.
Advanced Multi-Battery Intelligent Management
By default, whether charging two leisure batteries or a leisure battery combined with your vehicle's engine battery, the system optimizes power delivery seamlessly. It concentrates power on the main battery (connected to its BAT1 terminals) until it reaches approximately 70% charge. It then toggles over to bring your engine starter battery (BAT2) up to 70%, alternating intelligently between them until both banks are fully topped up.

The unit continuously monitors your electrical lines to maximize battery lifespans and safeguard internal wiring:
Frequently Asked Questions
An MPPT (Maximum Power Point Tracking) dual battery solar charge controller is a device that intelligently manages solar energy from your panels and distributes it across two separate battery banks — typically your leisure battery and your vehicle’s starter battery. Unlike basic PWM controllers, MPPT technology actively optimises the voltage from your solar array to extract up to 20% more usable power, regardless of weather conditions.
All installations are carried out at our specialist campervan workshop in Worcestershire, UK. Our technicians are NCC Academy trained, IMI EV qualified, and VCA aligned — ensuring your electrical system is handled to the highest professional standard.
Yes. The controller supports twin charging profiles, meaning it can manage a lithium LiFePO4 leisure battery and an AGM or lead-acid starter battery simultaneously, each with its own chemistry-specific charge curve. It also includes a LiFePO4 wake function to safely revive batteries that have entered a protective sleep mode.
The controller supports solar panel arrays up to 225W and accepts input voltages up to 68V, making it compatible with most standard campervan roof-mounted solar setups on 12V or 24V battery systems.
