VW Grand California: New Cables for AC & Heater – Run Off-Grid
Demand for enhanced off-grid capabilities for Volkswagen’s Grand California campervan is driving a surge in aftermarket upgrades, particularly relating to power management and air conditioning. Owners are seeking solutions to operate appliances, including heating and hot water systems, independently of traditional campsite electrical hookups (EHU) or diesel-powered generators.
The standard VW Grand California, while equipped with a 100Ah lead battery, is considered by many owners to be insufficient for extended off-grid use. , several online forums demonstrate a growing community focused on modifications to increase self-sufficiency. RV Installations, a UK-based company, reports a rise in requests to improve the off-grid performance of the vehicle, noting the standard battery setup is “wholly inadequate” for those intending to venture beyond established campsites.
One popular upgrade involves the installation of a Battery-to-Battery (B2B) charger, such as the Bluetti B2B 1, to charge auxiliary batteries while the vehicle is in motion. A user on the VW California Club forum, posting on , detailed their experience routing cables from the starter battery to the Truma heater area to facilitate the installation of a Bluetti battery system. The user, identified as “mr pg” and located in Suffolk, highlighted the challenges of cable routing as a key obstacle in the upgrade process.
The desire for these upgrades stems from a desire to utilize the Grand California’s heating and hot water systems without relying on external power sources or the vehicle’s diesel engine. A discussion thread on the VW California Owners Club explores the feasibility of using gas and electricity for heating and hot water during off-grid excursions, including the possibility of taking showers. The thread raises concerns about potential warranty implications and the cost of upgrading to lithium batteries.
The limitations of the standard power system are particularly noticeable when considering the energy demands of air conditioning. While the Grand California’s air conditioning is operational while driving, utilizing the vehicle’s dash controls, running it while stationary and off-grid presents a significant challenge. A YouTube video demonstrates the connection points for a 230-volt hook-up, highlighting the need for compatible cables and connectors, such as the 16A 230v premium VW California compatible hook-up cable offered by Toughleads, for accessing external power when available.
The trend towards off-grid upgrades reflects a broader shift in campervan culture, with owners increasingly seeking independence and the ability to explore remote locations. The Grand California, marketed as a premium campervan, is attracting a demographic willing to invest in modifications to maximize its capabilities. However, the potential for voiding the vehicle’s warranty remains a concern for some owners, as highlighted in the online forum discussions.
The European market appears to be at the forefront of this upgrade trend, with some owners utilizing portable power stations and inverters plugged into external hookups or, alternatively, into the vehicle’s electrical system. This approach allows for the use of standard household appliances and heaters within the campervan, further enhancing its functionality, and comfort. The avoidance of diesel generators, as stated by one forum user, underscores a preference for quieter and more environmentally friendly power solutions.
The complexity of these upgrades, particularly the routing of cables and the integration of new battery systems, suggests a growing market for specialized installation services. Companies like RV Installations are positioned to capitalize on this demand, offering expertise in power management and air conditioning solutions tailored to the VW Grand California. The ongoing discussions within online communities demonstrate a collaborative spirit among owners, sharing knowledge and experiences to overcome the technical challenges associated with these modifications.
The increasing popularity of the Grand California, coupled with the desire for greater off-grid independence, is likely to fuel continued innovation in aftermarket upgrades. As battery technology advances and more efficient power management systems become available, owners will have even more options for customizing their vehicles to meet their specific needs and preferences. The focus on lithium batteries, as discussed in the VW California Owners Club forum, suggests a growing awareness of the benefits of lighter, more powerful, and longer-lasting energy storage solutions.
