Upgrading from Flooded to AGM Batteries – What Setting Do I Change Including My Solar Controller?, on Jul 04, 2017 asked:

Last year I installed a Gioco 130W solar panel with a Genasun GV-10 Pb controller to charge my older flooded lead acid batteries along with a Victron BMV-700 Series battery monitor. I have just purchased brand new AGM batteries and I am wondering what steps I have to take before replacing the old batteries? - Heidi

Replacing My Old Batteries, on Jan 31, 2017 asked:

My house batteries on my 42 foot Nordic Tug are in need of replacement. I have 6 golf cart interstate batteries with 600 amp hours. I believe I have 3 choices: 1. Replace with the same flooded, lead acid batteries – around $1000 or less – least expensive but require maintenance and last up to 5 years 2. Replace with AGM 3. Replace with Firefly Carbon Foam Can you review what I have and how they are currently connected and then recommend my options with cabling for the new style AGM or Firefly. Can you provide Canadian pricing for the options? - Bert

Automatic Combiner Relay or Voltage Sense Relay, on Dec 01, 2016 asked:

Hi Jeff, I met you the other day while you were performing an Electrical Audit on a friend’s boat. You mentioned a product that allows you to direct excess power from one battery to another when charging. What is this called and how hard is it to install. – Rob

Can I Leave My Battery Charger "On" In Float Mode?, on Nov 02, 2016 asked:

I have lead acid batteries and a inverter/charger. The battery monitor is a Link 2000. When the monitor switches to the float mode, is it ok to leave the charger on indefinitely? – Doug

DC Only Fridge, on Oct 13, 2016 asked:

Thank you again for the audit and the install. I am delighted so far. The installer was very professional and seems to have got everything set up properly. As you know the battery monitor is great fun. I've been obsessively testing all my devices to see what load they put on my system. I have a question. My fridge will only work off my battery. How much damage am I doing to my house batteries if I leave it on all the time while connected to shore power with the batteries charging? The battery monitor says the fridge draws about 2.5 amps and 30 watts at the setting I would use. One obvious risk is if I lose power I would drain my house batteries. But if I eliminate that risk by checking in every few days will I be causing unreasonable wear on my batteries?

Reverse Polarity Light and a Portable Generator, on Oct 05, 2016 asked:

I'm up here in Prideaux Harbour and tried to charge my batteries and can’t. I have a Yamaha 2000 watt generator connected to the shore power - it worked with the old charger. However when the generator is connected, the 120 volt reverse polarity lite comes on (always has). Is the new charger sensitive to this, thus causing the charger to cut out? Is there a fix for this? - Dieter

Should I install an external fan for my inverter/charger? - Mike, on Apr 04, 2016 asked:

I would like to install a fan in the area that I have installed the inverter. I have cut two large holes to help with circulation but I still don't think there is enough ventilation. Is it possible to add a fan that operates automatically each time the inverter turns on?

What Tool Should I Use To Measure DC Current Draw - Mike, on Dec 16, 2015 asked:

I am the owner of the White ACB (Aluminum Chamber Boat) boat that you did an electrical audit on a couple of years ago. My question is do you have a recommendation for a good multimeter to measure DC Current draw that will not break the bank? I want to understand the current load of different items on the boat for planning the size of the battery bank, trouble shooting, etc. Would one of the Fluke clamp on style tool be a good bet?

Does My Inverter Draw More Than What My Alternator Creates? - Doug, on Oct 16, 2015 asked:

My SOC was 51% and my meter said inverting -7 amps. I started the engine at 1200 rpm and my meter says inverting 66 amps. Am I correct in assuming that I am putting 60 amps per hour into my batteries? So after a couple of hours I will have another 120 amps in the batteries and should be good for the night?

Useable Battery Capacity vs. Battery Monitor – Doug, on Oct 08, 2015 asked:

Can you please explain how many amp hours we have for use on our boat? We have two 198 Ah batteries. If we are not supposed to use more than 50%, does that mean we have 200 Ah to play with? Does this mean that we can run the battery to show 200 Ah used on our Link 10 monitor? I have noticed that the monitor itself is set up to indicate that we have 200 Ah. Should this be 400 or are the bar usage lights based on only 200 available hours? Or are they only showing 100 amps available for usage? Neither of us is clear on this. I hope my question makes sense.
