An interesting project - and great set up. I

Hello, in my boat (an old Cascaruda 1080) I want to renew the coming winter, the electrics and the Galley equipment. I got there a few ideas that I would like mchte discuss with you, even and especially to get one of you say which of my ideas why can not function. Currently, starter battery, two consumer batteries, a battery frs bow thruster, and a permanently installed gasoline generator for 230V are available. The gas generator was too loud anyway, and now isser endgltig broken and thrown portable steam table out. Between the two consumer portable steam table batteries had to switch portable steam table manually. The charge of the thruster battery was Glckssache. Refrigerator and stove / oven have reached the end of its intended life already far behind. Stove, oven and refrigerator were operated at 50 mbar gas and would have to now in the overhaul anyway out completely and replaced with 30 mbar. The gas system will be suspended. What I want to achieve: - Power consumption including cooking, baking, coffee making facilities, fridge, computer, TV, light, etc ...: about 1 to 1.5 kWh daily - simple and Clearly arranged installation, low-cost devices portable steam table te without expensive "yacht" gimmicks - clean separation of all three Batteriebnke - secured load all Batteriebnke in all modes - largely automatic operation portable steam table - electric stove and oven (gas cooker, and thus fly the whole gas installation out); fr 's emergency is a spirit stove on board - constantly 230V for small consumers (load devices, computers, TV ...) - at least 3 days (better than 1 week) self-sufficiency without machine operation portable steam table - shore power only in exceptional times as I want to achieve it : - about 500 Wp solar modules (two 250 Wp modules fit on the roof) - 600 Ah service batteries - 200 Ah Bugstrahlruderbatterie - 200 Ah starter battery - 200 Ah backup battery - 1500W Wechelrichter with shore power-priority switch to backup battery - 60A to 100A charger at 1500W inverter . This invites separated (automatic charging current distribution) starter battery and consumer banking - a bow thruster has its own small charger (max 20A) at the 1500 W inverter (to be thick 12V cable unnecessarily) - the backup battery is charged by alternator portable steam table and PV modules - 3000 W inverter for kitchen (two induction plates, kettle, coffee maker, microwave / hot air) to consumer banking is thus ensured that the Batteriebnke are cleanly separated, and that each bank always gets optimum charging current. The 1500W inverter air forever, and so are always 230V for small consumers to Verfgung. The automatic shutdown this 1500W inverter with low voltage portable steam table ensures that the backup battery is not completely discharged and destroyed. portable steam table If the 3000W inverter for heavy load on the kitchen and you have to save power, so the machine can run the way to deliver over the alternator ever good the half of the required power. Assumptions and Rechenanstze: portable steam table - The Bank offers consumer-600Ah at 50% DOD 3.6 kWh (with discharge of the backup battery can even be taken from 4.8 kWh), but wg losses in the inverter and charger still with about 20% deduction must be loaded. Without any charge the battery bank that is enough for 3 days. - The 500 Wp solar modules portable steam table supply at very good weather 1 kWh (alignment on the boat is suboptimal, otherwise you knnte even 1.5 to 2 kWh fix). On average, I calculate portable steam table daily with 0.5 kWh. This means that one weeks self-sufficiency without machine operation possible - at a half-empty battery bank (only then is full current draw possible) Gengen 2h machine running time for recharging the daily consumption, with average sun exposure enough already 1h - the costs are limited: ca 600 for the solar panels with charge controller, batteries for 1200, 800 for the inverter, 600 for the charging switch 100 for the Indukationsplatten and 200 for microwave / oven.

An interesting project - and great set up. I'm also just about something for preparing winter. I recommend you dignity times to view the Mastervolt LioN batteries. The piece has 320 A, but can be discharged almost completely (ie almost 100% DOD) and at 1C - ie you have the 320A if you leersaugst also to Verfgung, the entire Capacity in an hour . In normal batteries, the Available Capacity portable steam table falls immediately to a fraction of the Nennkapazitt once you entnimmst Enlarged Entladestrme. eg a 200Ah gel battery has 200Ah Capacity, if you but they entldt portable steam table in 20 hours only 110Ah Capacity, portable steam table if you entldt in 60 minutes. Why am I writing portable steam table this to you? Because it affects you - you mchtest much work to me the inverter and you suck a lot of power in a short time from the batteries when you anhngst a corresponding portable steam table load. Look on the DATASHEET your batteries, how much electricity they deliver, if you in a short
