Solar charges your battery bank when the sun is out. A secondary alternator charges it while you drive — any time, any weather, any season. For vehicles with high continuous power demands, a secondary high-output alternator is often the most reliable charging source in the system.
Voltara Systems installs secondary alternators for vans, trucks, and specialty vehicles in Long Beach, CA.
Your vehicle's factory alternator is sized for the stock electrical system. Adding a large auxiliary bank load stresses it, shortens its life, and still doesn't charge fast enough.
Solar fails in overcast weather, winter months, and indoor parking. An alternator charges the bank every time the engine runs — regardless of conditions.
A high-output secondary alternator delivers 200–320A — up to 4,500W of charging while driving. More than most solar setups produce in a full sunny day.
Dog grooming vans running high-draw equipment continuously throughout the day. Mobile offices that need to keep a large battery bank topped off during transit. Builds where solar is insufficient — heavy tree cover, indoor parking, northern latitudes, winter months. Any application where reliable charging while driving matters.
We design the charging circuit correctly — including the right DC-DC charger or lithium-compatible voltage regulator — so the alternator and the battery bank work together without damaging each other.
For vehicle alternator standards and specifications, see vehicle alternator standards and specifications from SAE International.
Yes, with the right DC-DC charger or lithium-compatible voltage regulator between the alternator and the bank. We design the charging circuit correctly so the alternator isn't damaged by lithium's charge profile — this is a critical step that many installs skip.
A high-output secondary alternator can deliver 200–320A depending on the unit and installation. At 14V, that's 2,800–4,500W of charging power while the engine runs — significantly more than most solar setups produce in a full sunny day.
We recommend checking with your dealer for your specific vehicle and warranty situation. We install using best practices and quality components to minimize any impact on the vehicle's existing systems.
