The electrical system is the heart of the ship and extents the time of freedom being off grid. The outdated Amel system needs an upgrade. We eventually want to go to Lithium (LiFePo4) batteries because the current gel batteries lost their capacity. Currently off grid we have to run the generator 2x 1.5 hours every day. Secondly we prefer to reduce the number of hours of the generator, have it run shorter periods and at full power. The Amel system actually appears to have no fuses at all on large consumers such as the bow thruster (485 A). Only the end users have 16 and 10 A automatic fuses. So it is decided to overhaul and upgrade the entire system. Based on Lithium (Lifepo4) we also like the possibility of an induction stove. As a result the current 1500 W inverter is changed to a Victron Quattro II of 5000 W. All in all quite a large modification of the current system for which we need professional help. We found Arnold de Maa of ICT Nautic willing to make a proposal and execute the larger technical part of the installation. With help of our friend Joris we install all the wiring and the new solar panels ourselves. The first wire scheme is made in January 2022. Before the summer holidays, the vast majority of the system gets installed except for the new batteries. This way we are able to test the system and find any teething problems. Already we notice a huge improvement. We can use the consumers much freer without worry due to the larger inverter and extra solar with less generator hours per day. After the summer holidays, the new sets LiFePo4 batteries are delivered by PureAcell on 25 August 2022. Two sets of 8 cells each or 7.5 kWh/ 280ah. Total so 15kW/560 AH by 24 V. These are installed end of August, together with the remaining parts. Everything just ready for our yearly sail trip with the Tempo34 group. This time to London. The improvement with the LiFePo4 is enormous. No fear for crew using multiple electrical devices at the same time. We do however discover that the Eve Lithium cells supplied are not the A cells that were ordered. Cell 2 of the SB battery and cell 7 of the BB battery are not ok. A small set-back but Puracell immediately confirms that both sets will be replaced. For the time being, the current sets are good enough to complete this season. An advantage is that we will start our circumnavigation in 2023 with fresh set of A quality batteries. Ultimately, the new sets are delivered by Puracell in March 2023. The last adjustments and fine tuning are made by ICT Nautic and the conversion of the electricity is complete in May 2023 before the start of our circumnavigation.
