The Victron Energy SKYLLA IP65 12/70 (1+1) charger is a robust, high-performance battery charger specifically designed for demanding installations. It combines intelligent charging for a wide variety of battery chemistries with a durable, weather-resistant enclosure (IP65 rated) that makes it suitable for marine, mobile, industrial, and harsh-environment applications.
In the “12/70 (1+1)” version, the unit delivers 12 V at up to 70 A on the main output, plus a second isolated output of ~3 A for a starter or auxiliary battery.
Its wide input-voltage range ensures full output power worldwide, and the adaptive 7-stage charging algorithm (plus dedicated Li-ion mode) helps maximize battery life and performance.
Features & Benefits
- Adaptive Smart Charging for Longevity : The 7-stage adaptive algorithm ensures that lead-acid batteries are fully optimised: bulk → BatterySafe → absorption → equalisation → float → storage → weekly refresh.For lithium batteries the algorithm simplifies, yet allows direct integration with a BMS (battery management system) via remote control or CAN-bus. This contributes to longer battery life, reduced maintenance and better performance.
- Universal Input Voltage : With an input range of 90-265 VAC, the charger can handle fluctuations common in many Tanzanian installations (remote sites, generator or solar coupled systems, unstable grid). It will maintain full output even when input voltage is lower than ideal.
- Rugged, Environmental-Ready Housing : The IP65 rating means the unit can be mounted in locations exposed to dust, humidity, salt air (e.g., coastal Tanzania, boats, safari vehicles, off-grid lodges). This expands installation flexibility (engine room, outdoor shelter, vehicle).
- Parallel & Networked Operation : The CAN-bus system allows multiple units to be synchronized and controlled together—useful for larger installations (e.g., backup power banks, commercial installations) where multiple chargers must coordinate their charging.
- Secondary Output for Starter Battery : The “1+1” model provides a small dedicated output (3 A) for charging a starter battery alongside the main service battery bank—ideal for marine engines, mobile vehicles, or generator start batteries.
Use Cases
- Marine / Coastal Boats & Catamarans : On boats operating in Lake Victoria, the Indian Ocean coast (Dar es Salaam, Zanzibar) or charter safari boats, where salt air, humidity and battery systems require robust charging. The IP65 rating and adaptive algorithm fit perfectly.
- Safari Vehicles / Mobile Units : 4×4 overland vehicles, mobile clinics, remote lodges or camps that have DC battery banks (12 V) supporting lights, refrigerators, communication gear. The wide input voltage range supports installations where grid power is unreliable or generator driven.
- Off-Grid / Solar Hybrid Installations : Small to medium lodges, guest houses, remote telecommunications sites or field stations using 12 V battery banks (AGM, Gel, Lithium). This charger can integrate into the system, maintain battery health, and manage different battery chemistries.
- Commercial / Industrial Backup Systems : For businesses (ICT data rooms, telecom towers, rural business hubs) relying on battery banks for backup power. The synchronized parallel capability allows scaling up with multiple units.
- Marine Shore Power / Engine-Room Integration : In situations where the battery charger must stand up to engine-room conditions (heat, vibration, salt humidity) and provide reliable service battery charging while vessel is moored or underway.
Value Propositions
- Reliability in Challenging Environments: With IP65 protection and rugged construction, the charger can handle harsh ambient conditions common in Tanzania (high ambient temperature, tropical humidity, dusty environments, fluctuating mains supply).
- Flexibility & Global Input Compatibility: The wide input range ensures compatibility with local generator supply, unstable grid, or remote micro-grid systems. One model covers multiple voltage regimes.
- Battery Life Optimization: The adaptive charge algorithm, temperature compensation, voltage sensing and storage mode combine to extend battery longevity. This is especially valuable where battery replacement is costly or logistically difficult.
- Smart Features & Future-Proofing: The CAN-bus communication allows monitoring, synchronised parallel operation and integration into wider battery/energy management systems – attractive to commercial installers, telecoms, lodges and industrial users.
- Multiple Battery Banks & Dual Outputs: The ability to charge a main service battery and a starter battery simultaneously (via isolated output) suits vehicles, boats or systems with service + engine batteries in one unit, streamlining installation.
Local Market Positioning in Tanzania
- Off-grid residential/holiday homes (solar + battery)
- Commercial establishments (lodges, restaurants with backup power)
- Marine/fishing boats on Lake Victoria / Indian Ocean coast
- Telecom/industrial installations (battery backup for towers, remote sites)
- Mobile vehicles (safari trucks, service vans) with dual battery banks
- Designed for African conditions”: heat, humidity, variable power supply
- Works with generator, solar or grid inputs — suits rural/remote areas
- Protects expensive battery banks and ensures long-term reliability
- Single-unit solution with dual-bank outputs simplifies installations
- Brand reputation: Victron is globally known for quality and support
- Ensure local installer understands correct wiring, ventilation and mounting (especially for forced ventilation, as charging current will drop if ambient >40 °C).
- Stock appropriate cables (battery cable sizes are important: e.g., for up to 6m cable and 70 A current use 16 mm² copper or as per manual).
- Educate users about battery bank size matching (recommended 350-700 Ah for the 12V/70A model) to get full benefit.
- After-sales support: emphasise Victron’s global warranty and availability of spare parts; reinforces value in the Tanzanian market where support is highly valued.
- In Tanzania, buyers may compare Chinese or lesser-brands. The pitch should emphasise durability, brand, IP65 rating, smart features and long-term cost-of-ownership savings (battery life, less downtime).
