 86LB  86  37.2 24V 48A  1152W   22KM/H

   

   Engine used is the  62 lbs model with brushes, 12 volts supply, 5 speed forward and 3 backwards, with original propeller consumption is lower than manufacturer test:

-first speed 18 amps 

.....................

-forth speed 25 amp

-fifth speed 41 amps

   Still present engine has run more then 140 km, mostly done in trips to Danube Delta and Dorobantu channel, were I run 5-6 hours/day, and even in Danube upstrem without any problems. Is a very reliable engine, easy to mantain, also cheap to buy.

 

    2.Electric Motor 86 lbs, 24 Volts from our partner http://www.carponizer.ro/motor-electric-barca-86lbs-cu-3-pale-model-daiwa.html

    At a first impresion that engine has the same propeller as the 62 lbs version, of cource with a higher rpm. From the data sheet this engine should use less amps than 62 lbs, 12 volts version. In the next spring I will test  him.

 

   3.Solar panels i choose flexible type for lower weight and higher efficency of 22%. I buy them from here

I have 6 panels of 50 w each, beause I can wiriing them at 12 V in parallel and 24 v in series-parallel mode. Until now solar panels work flawless, manufacturer give a 25 year life span for panels with 80% innitial cappacity.

 

  Solar panel specifications:

  •    Peak power: 50W
  •    Maximum power voltage: 17.8V
  •    Maximum power current: 2.84A
  •    Open circuit voltage: 20.8V
  •    Short circuit current: 3.04A
  •    Power allowance range: +/- 5%
  •    Dimensions: 555*535*3 mm
  •    Weight: 1.1 kg
  •    2x0.9m of high quality single core solar cable 2.5mm cross section
  •    Male and female MC4 connectors
  •  
  • 4. Solar controller   this is a must in your solar configuration because they can manage entire charging-discharging process using special design algoritm for different type of batteryes.There are 2 version of controller with PWM charge and MPPT charge.

  •  
  • PWM 
  •  
  • In the begining when I have a 12V trolling motor  I used this PWM option, 60 amp, with good results. When you choose an  solar charger you have to take care that the amps they supported (charging-discharging) must be higher than al your electric consumer used.
  •  
  • MPPT
  • I pllaned to change my solar controller with this Fast MPPT and solar panel's array. Diference between them is in efficiency, MPPT is a more efficient charger with 95 % efficiency. The solar panels would be connected in series giving an impresive 120V with 2,5 amps, from here MPPT controller will reduce voltage to nearly 24V.

  •   5. Battery  on the market is available a multitude of chemistry Pb, NiCd, NiMh, LiPo, LifePo4, Li-Ion, etc price depends of their performances. For home use in  solar configuration  Gel lead or AGM in most common way to storage energy because their lower buying price, their main disatvantage is higher weight. A cell nominal voltage is 2V an Lead battery GEL or AGM of 12V has 6 cells in series. In first test I used a Lead Gel battery or 12 volts and 110 amps cappacity, wich worked  well with a decent range of usage http://prowatt.ro/12v110ah-gel-deep-cycle-batt-p-162

  • Data sheet for Agm or Gel battery here

  •  
  •     For now I gave up on Lead gel battery and invest in a more powerfull  and light battery LifePo4 or LPF from Victron enegy http://prowatt.ro/lithium-battery-128v90ah-cb-p-204 .This is the safest Lithium battery on market today with far more energy density, lower weight, high current of charging-discharging and greater cycle rate then the Lead Gel or AGM. LifePo4 battery require increased care comprared to lead batteries, internal cells should be equalized and also must not excced certain values of charge 4.2V/cell, to discharge 2.5V/cell, overcoming this values lead to premature battery failure. Batery protection is trought a BMS with connection to Battery Protect or Cyrix unit and equalize trought a dedicated equalizer. A cell nominal voltage is 3,2V an LFP battery of 12.8V has 4 cells in series.

    •  
  • Battery Management Sistem VE.BUS BMS: is an external drive that is designed to read information sent by BMS's internal battery and comunicates with a Cyrix unit or Battery Protect: 
  • -stopping or disconnect load when a LPF cell (LiFePO4) is discharged below 2.5V (under this voltage cells    irreparably spoil)
  • -reducing charge current if a cell overload more then 4.2V or temperatura increase;
  • -stopping the disconnect of chargers in case of exceeding voltage 4.2V/cell or temperature
  •  
  • Data sheet here
  • Battery Equalizer: is an external unit used for proper equalization of at least 2 both lead or LFP batterier when they are connected in series, parallel or series-parallel. In my case the circuit voltage of 24 V, when charge voltage of entire system exceeds 27.3V, equalizer starts and will compare the voltage of the two batteries will drain the battery 0.7amps filled with a task so that at the end of loading process voltage of all batteries should be the same. It has ability to display various parameters using the smartphone app Victron Smart Connect via Bluetooth dongle VE.Direct.

BMV-700 monitoring system: it is an exterrnal drive that is designed to display: battery voltage, current consumption in amps-hour, time away from current consumption etc. You can use both type of battery Lithium and Lead. It has opportunity to display these parameters using the smartphone app Victron Smart Connect via Bluetooth dongle VE Direct.

Mains Charger: I opted for a charger powered IP 67 220V with output of 24V/12amps, with electronic components embedded in resin, virtually submerged with various protections. Because lead batteries and LPF  use the same algoritm for charging, this charger can be succesfuly used for both types of batteryes, producer granted 5-year warranty. This type of charger is available in several version 12V/7amps, 12V/13amps, 12V/17amps, 12V/25 amps, 24V/5 amps, 24V/8 amps, 24V/12 amps. Variants of chargers ending 1+Si have option to use it as a power source for 12V or 24V.
