Hi Paul, many thx for explaining the differences! I have the big grey box installed in my rig. I had a look at these green boxes and was a bit surprised as the a very pricey?! I wasn't aware that the green box comes with mppt solar and booster for 14.xx volt! Now - after nearly seven years in service! - the Victron gel battery is about to retire and I'm looking for a replacement. I thought on getting lithium cells instead of lead acid/AGM. I'm not using the alternator anymore for charging as my single solar panel with its own mppt controller is sufficient to recharge what my fridge and some lights at night consume. Will the (grey box) electronic coop with the higher system voltage? Or will it constantly beep as it is on over voltage?
Hello, This will depend on the input voltage coming from the current MPPT solar controller. IF you're adding lithium batteries to your system, you need to confirm whether your controller is lithium compatible. The alarm in the Power Pack will alert if input voltage levels are above 14.65v. If your solar controller, set to lithium, charges above 14.65v (probably doesn't), it will sound the alarm. You can turn off the alarm as well. Hope that helps.
Paul - I have in mind a DC-25 Power Pack with a lithium battery. If I wanted to have 2 such batteries in my truck bed camper, would that suggest using two DC-25 Power Packs, or is there some other means to have 2 lithium batteries? I would want to be able to charge them via (a) my truck alternator; (b) via 110 if at a location with wall power, and (c) via solar panels. Thank you!
Steve, This is absolutely doable, great question! You could link multiple battery boxes but we would suggest a DC25 linked to the Aux Battery Box rather than another DC25. You do not need two chargers in your system. You would wire the two batteries in parallel and you can still charge via the alternator, the solar input on the DC25 unit or by plugging an AC battery charger into the charge port on the DC25. We like the NOCO line of chargers. Keep in mind, the more batteries you have linked together, the longer the charging timeframes can be, depending on the charge current from a charger or panel, and the depth of discharge within the batteries. Lots of variables here but absolutely doable.
Greetings. I own the National Luna portable power pack. I have connected it with the main car battery through the red anderson coupler. I just want to clarify, the grey anderson coupler can be used as an output (can connect an inverter, 600 watt max), and connect solar panels through a controller? Thank you Sir
Hi there, you are correct. The grey anderson couplers are rated to 50 amps max. This equates to approximately 600w @12v. Larger inverters will quickly exceed 600w though so make sure you check the specs on your preferred inverter. As long as there is a solar controller or regulated panel being connected, you can also use those grey connectors for an input. Do not connect a panel without a solar controller. Sounds like you've got it covered! Nice job!
Hi Andre, the DC-DC system from National Luna will adjust voltage levels for various charge cycles, regardless of the voltage coming from your alternator. When you select a specific battery type on the charger, this will change the charging profile for whatever battery chemistry you select on the charger. Most folks are using AGM or Lithium Iron Phosphate these days, this system is compatible with both and will charge both options efficiently. Hope that makes sense!
The standard grey powerpack is not adjustable. It's going to relay the charging current and voltage from the alternator to the aux battery. There is no change to the voltage unless you use the DC-DC system.

Very good product bolts off them, good info thank you

Paul- I do have a DC-25 Power pack. Can I use a DC-DC charger with it to set the voltage to above 13.5 V?

Sorry a I have Power pack
