CTO Stefan btw was one of the designers of the first 3 models of electric car quickcharge systems here in Sweden (30min for a fully charged car), and inresol both had and currently have car related projects under NDA, so the knowledgelevel inhouse at inresol is at the forefront of automotive electric car industry. So while old type low voltage led-acid batteries for sure will work, the question i guess is for how long. However, that said, since the internal N preassure is controlled and adjusted automatically I suspect you still need the computer part.Īs for your battery bank, are you sure its up for the job? The inresol batteries are high-tech 300V (or was it 600V) batteries with internal individual cell monitoring and load balancing, with individually tested components before assembly and specifically designed containers to ensure the battery doesnt overheat during the heavy 5kW input/output loads. The answer is no, they will sell units eg without the pellet burner as well as barebone engines. Since I was thinking to possibly run the engine with a rocket-stove I did ask if one needed to buy the whole thing. Just interested in the technology as well as purchasing a unit for myself. The public should be able to purchase units from about May-June.įinally, I have no affiliation to Inresol in any way or form. The parts are mainly produced in Sweden, by high quality producers, not from cheap imported Asian parts to lower cost but potentially also quality. Having extra batteries further extend the life of the batteries due to lowering the load and temperatures during peak power output. The included battery and extra batteries are produced inhouse, and containes internally developed circuitry to lower the load and extend life of the battery. If wanting to heat it with other fuels than eg pelleted wood, the engine comes with two 65mm inlets/outlets to which any other heatproducer can be connected via insulated pipes. This gives extremely low levels of foregin particles inside the engine and thus little to damage it, and the same concept was used on a small 500W engine in the 1950ies produced by Philips (mainly for far off placed radios). The engine internal Nitrogen preassue is automatically monitored and an N-filter generates N and pumps it inside the engine whenever needed. A complete sealings and bearings replacement should cost about 600 euro. Recomended maintainance interval is 20.000h (10-11 years normal operation), but the bearings according to spec should last 90.000h if the engine is never run too hot.

Also, my conclusion is that if using the unit also for heating your house, the 6% generator and 2% battery "loss" turns into heat that heats your house, ie no actual loss at all. The gererator itself is at 94% efficiency and the loss of energy in the battery is about 2%, but working towards a batterybank allows the engine to run much more optimally than if having to sync to eg 50Hz/60Hz AC (20-25% more efficient). So for maximum electrical output (30%-ish), 900 C is the optimum target, which likely is at all times except possibly during cold winter conditions.
Less lowers the sterling engine performance, higher produces more heat than "the engine can make efficient use of". The engine performs best when "fed" about 900 C heat continously. The electric output has been measured to 22-30%, depending on a large amount of factors (height above sea-level, fuel used, etc, etc). Info taken from memory, so take it with a pinch of salt.
So thought I´d pass on some of the info here.

Had some free time today so called inresol and had a well over 1h conversation with CTO Stefan.
