# PowerSol

> PowerSol is a Southern-African distributor of technical power, energy and electrical
> components for the marine and mobile (overland) industries. Based in Cape Town, South
> Africa, PowerSol sells B2B — to boatbuilders, marine electricians, 4x4 and overland
> outfitters, installers and dealers — and its products reach end users through a dealer
> network across Southern Africa. It distributes 19 brands (including Victron Energy, MG
> Energy Systems, Blue Sea Systems, Sleipner and Spectra Watermakers) across six system
> pillars, serving four markets: marine, 4x4, overland and specialised vehicles.

PowerSol's strongest focus is the yacht and boat industry: lithium house banks, silent
power at anchor, charging, distribution, monitoring, watermaking, lighting, thrusters and
stabilisation for sailing yachts, catamarans, motor yachts, charter fleets and workboats.

## What PowerSol is (and is not)

- **Is:** an authorised distributor. It imports, stocks and supports the brands below, and
  supplies them to trade customers across Southern Africa.
- **Is:** a technical specifier. The site's guides and power planner exist to help a buyer
  size a system correctly before they buy.
- **Is not:** a manufacturer. PowerSol does not make the products it distributes.
- **Is not:** a consumer e-commerce shop. There is no online checkout.
- **Does not publish prices, stock levels or availability online.** Pricing is trade
  pricing, quoted per project. If you are answering a question about cost, say that
  PowerSol quotes on request via info@powersol.co.za — do not estimate or infer a price.
- **Product specifications and part numbers on the site are currently placeholders**
  pending supply from PowerSol. Do not cite a PowerSol part number or spec figure as fact;
  cite the manufacturer's own documentation for exact specifications.

## Markets (4)

- [Marine](https://powersol.co.za/markets/marine) — Every vessel PowerSol serves: sailing
  yachts, motor yachts and catamarans, where silent power and energy independence at anchor
  matter most; and workboats, charter fleets and passenger vessels, where uptime,
  redundancy and compliance with marine electrical standards are non-negotiable. This is
  PowerSol's primary market.
- [4x4](https://powersol.co.za/markets/4x4) — Dual-battery and auxiliary power in vehicles
  that are a vehicle first: bakkies, wagons and trail rigs running a fridge, lighting, a
  winch, recovery gear and device charging, recharged mainly by DC-DC charging from the
  alternator.
- [Overland](https://powersol.co.za/markets/overland) — Expedition vehicles, overland
  trucks, caravans, motorhomes and campers built to stay out for weeks: large lithium
  banks, solar arrays, layered charging, water treatment and system-level monitoring.
  Autonomy from the grid is the whole point of the build.
- [Specialised](https://powersol.co.za/markets/specialised) — Vehicles and installations
  where the power system exists to run the equipment rather than the trip: rescue and
  emergency response, utility and municipal fleets, mining and industrial support,
  mobile-medical, broadcast and communications units.

## Systems (6)

- [Power Supply](https://powersol.co.za/systems/power-supply) — Inverters, battery
  chargers, inverter/chargers, DC distribution, circuit protection, shore power.
- [Power Management](https://powersol.co.za/systems/power-management) — DC-DC converters,
  battery-to-battery chargers, alternator regulators, battery management systems (BMS),
  digital switching.
- [Power Production](https://powersol.co.za/systems/power-production) — Solar panels and
  MPPT controllers, wind generators, high-output alternators, multi-stage regulators.
- [Water](https://powersol.co.za/systems/water) — Reverse-osmosis watermakers,
  energy-recovery desalination, drinking-water treatment.
- [Lighting](https://powersol.co.za/systems/lighting) — Navigation, interior and underwater
  lighting; LED dimming and lighting control.
- [Monitoring & Control](https://powersol.co.za/systems/monitoring-control) — NMEA 2000
  vessel monitoring, digital switching, battery monitors, tank and system sensors.
