The Filmhybrid 100 heralds the next generation of environmentally friendly hybrid power generators for the film and media industry. It combines different operating modes in a unique way. With small to medium loads (up to 12KW), the system is completely supplied by the battery pack. This has a system capacity of 18KWh, of which at least 12KWh can be used in everyday operation. If, for example, only a few camera batteries and cell phones are charged on an outdoor day shoot, the total output is around 0.5-1.5KWh. With this load, the battery capacity is sufficient for a full day of shooting.
As soon as the load requirement increases or the batteries have to be charged, the LPG (liquid gas) powered generator starts automatically. This has an output of 85KVA and has, thanks to the gas engine, very low emissions (no fine dust, hardly any nitrogen oxides and significantly less CO2).
Facts and figures:
– System output 100 KVA
– Intelligent control combines the cheapest and cleanest energy sources depending on the load condition: integrated battery storage, LPG gas generator, photovoltaic modules, grid feed
– Battery capacity: 12 KWh usable (system capacity 18KWh), AGM-Batteries 99% recyclable
– Photovoltaic panel 1KW peak
– parallel power supply possible
– 85 KVA gas-powered electricity generator (LPG)
– No emissions in battery operation; significantly reduced emissions in generator mode (no fine dust, hardly any nitrogen oxides)
– very quiet, inaudible in battery mode; less than 48dBa in 7m in generator mode
– built as a self-propelled machine with a total weight of 7.2 t (very mobile and flexible) – Euro 6
– LPG is an environmentally friendly alternative to diesel with good availability and low costs
Background and details:
The central interface of this new power generator is the intelligent control of Mobilhybrid. The control always selects the best energy source according to the following parameters:
– Solar> always as soon as available
– Network> always as soon as available
– Batteries> as long as possible
– LPG engine> as soon as there is additional demand
Why LPG instead of CNG? Our goal was to develop a self-sufficient film power generator that can deliver electricity for at least one long day of shooting at 90% full load. CNG is stored in gaseous form at 200bar, so the tanks would have weighed 6 times as much as LPG tanks and required 2.5 times the space. So it would not have been possible to accommodate the required tank capacity on a < 7,5t truck. Film units are often used in remote areas where there is no other power supply. The fuel supply was therefore an essential decision criteria. For LPG there is a ten times denser filling station network than for CNG, which is particularly important for filming in rural areas.
For the batteries, we opted for high-tech AGM-Batteries. These are significantly heavier than their modern relatives lithium ions or lithium iron phosphate. But they are not considered to be dangerous goods, are much more robust and have a higher temperature tolerance (LiIon or LiFePo batteries require active temperature management). And lead-gel batteries are 99% recycled. We are working on increasing the battery capacity. As soon as appropriate batteries are available or the regulations regarding dangerous goods are changed, double or triple the battery capacity is realistic.
