Balmar
High-output DC charging from your engine.
Balmar is a specialist in engine-driven DC charging: high-output alternators, multi-stage external regulators and battery monitors engineered to charge demanding house banks. PowerSol distributes Balmar for marine and overland installations across Southern Africa.
Most engines leave their standard alternator and internal regulator in place, which charges a starter battery adequately but recharges a large house bank slowly and incompletely. Balmar addresses this with high-output alternators sized for serious house loads, paired with multi-stage external regulators that control the charge profile rather than relying on a fixed internal setting. The result is faster recharging during engine run-time and a fuller battery at the end of it.
External regulation is central to the Balmar approach. A separate multi-stage regulator manages bulk, absorption and float behaviour, and supports the charge profiles that modern battery chemistries require — including the tighter voltage and temperature control expected by lithium banks. Temperature sensing on the alternator and batteries protects both the charging hardware and the cells, so output can be pushed without cooking the alternator or overcharging the bank.
Battery monitors complete the picture. By measuring current in and out of the bank, a monitor reports true state of charge rather than a voltage estimate, giving installers and crew an honest view of remaining capacity and charging progress. Together, the alternator, regulator and monitor form a coordinated charging system rather than a collection of parts — which is why Balmar is specified on boats and overland vehicles where engine charging is a primary, not secondary, source of power.
Why specify Balmar
- High-output alternators sized for large house banks, not just starting duty, so engine run-time does real charging work
- Multi-stage external regulation with selectable profiles, including the controlled charging that lithium banks require
- Alternator and battery temperature sensing to protect charging hardware and cells under sustained high output
- Alternator, regulator and monitor designed to work as one coordinated charging system, simplifying specification and commissioning
Balmar — FAQs
Why fit a Balmar alternator and external regulator instead of the engine's standard alternator?
A standard alternator and internal regulator are tuned for starter batteries and tend to recharge a large house bank slowly and only partially. A high-output Balmar alternator with a multi-stage external regulator delivers more current and controls the full charge cycle, so the house bank recharges faster and more completely during normal engine run-time.
Can Balmar charge a lithium (LFP) house bank?
Yes. Balmar's multi-stage external regulators support the controlled charge profiles lithium banks require, with the tighter voltage limits and temperature sensing needed to charge safely. Confirm the correct regulator profile and any battery management requirements for your specific bank with PowerSol before commissioning.
Do I need a battery monitor as well as the alternator and regulator?
It is strongly recommended. A battery monitor measures actual current in and out of the bank to report true state of charge, rather than inferring it from voltage. This gives an accurate view of remaining capacity and charging progress, which is particularly valuable on vessels and vehicles that rely heavily on engine charging.
