Hi all it has been suggested to me that I should use a plasmatronics regulator to look after my batteries and prevent overcharging etc. What are other people using and what do you think of the idea of using the solar reg for wind?? On a similar topic I have moved both my 24V battery banks and am contemplating a completely new board for fuses, meters, regulators, switches, inverter and battery charger etc. Has any one suggestions or links that may be helpful. cheers robert 1555 W grid connect system since Jan 08 both vehicles running on modified, used vege oil. |

Robert, solar regulators are by and large unsuitable for wind turbines because they may short out the incomming power from the solar panels or open circuit it. I am too lazy too look up the Plasmatronics regulator but am quite sure it falls into the above. Both are destructive to a wind turbine, to accomadate any excess power from a wind turbine you need a controller that can activate a dump load that will keep the wind turbine loaded but "waste' the excess power. As to new control panels what are your requirements, I used a piece of MDF which I painted with chalk board black,(I can write on it) to which I mount everything. Dont forget that fuse boards etc are normally mounted on a panel (name escapes me) that is not combustable, for very good reason. I included a junction box for all shunt cables to be combined prior to the cable for remote metering, it's neater. If your circumstances allow it a cabinate into which every component is mounted is very desirable, but here one must take into account heating and cooling. This allows a cleaner enviroment for those controlls, dust and moisture is a major killer of inverters etc. Not to mention it can be locked to adress regulatory requirements. allan down under "I like this place and willingly could waste my time in it" - (Act II, Scene IV). |

Hi Robert , The plasmatronics regs work very well as wind regs , all the info is on their site . Depending on the max output of your mill you and the size of your dump load if under 20 amps the PL20 can do an execellent job as it can be configured in program 4 to your requirements .. I suggest you download the manual and wind plan 1 and 2 from their site..... Phill..

The LSet needs to be set correctly as well if using the internal MosFet. Gordon. become more energy aware |

Thanks guys, I bought a PL40 on ebay, so should be ok, at the moment my two F&Ps are down for work/mods but the chinese mill is working a treat with the strong southerly here. I like the feature of the PL40 that allows a second battery set to be the dump load after the first set is charged. I have two sets of 24V @ 650AH, and it has been a real mission to look after them, so looking forward to the relief of automation. I will down load the suggeted info thanks Phil cheers Robert 1555 W grid connect system since Jan 08 both vehicles running on modified, used vege oil. |

Hi Robert, I am using a PL20 with my 2 windmills, 24V battery setup now. I had previously used a picaxe controlled diversion load. I have now successfully interfaced the PWMout load pin of the PL20 to a 24VDCnom-60VDCnom boost converter. The 4point SOC battery maintenance settings are providing a much better charging system than the picaxe could. I am recovering battery capacity that had become unusable. I think that I have pushed back the battery replacement for a few more years and am now confident that when the time comes to replace the battery, that a new battery will have a better chance of a longer life. I am intending to look at a 7cell LiPo replacement of my 24V Pb acid system. Did you find the LOAD output control current sufficient on the PL40, or have you used a relay?

H Gordon, I used a relay, and all went well for a few days till the coil in the relay went shorted turn. This had the effect of letting a lot of smoke out of the PL40!. I have not had time to get back to look at it, just simply pulled it out of circuit and connected the mill to the second bank. I hope to get one of my electronic tech mates to have a look at it. cheers Robert 1555 W grid connect system since Jan 08 both vehicles running on modified, used vege oil. |
