Question:
Hello I am in need of a new inverter/converter for my camper, doing research I believe you guys have the replacement I need, I just would like to confirm I am correct or not. My inverter model number is PD4590K18L and on your site it looks like I can replace it with PD4590K18LS8
asked by: Trevor C
Expert Reply:
That is correct Trevor! The Progressive Dynamics 4500 Series RV Converter w/ Charge Wizard and AC/DC Distribution Panel item # PD4590K18LS8 would be the correct replacement. This is a 90-amp 2-in-1 AC/DC distribution panel and converter charger that is compatible with lithium and lead batteries.
If you're just wanting to upgrade your PD4590K18L power center to be lithium compatible and it was made after 2017, I recommend the Progressive Dynamics REL 90A 4500 Series Inteli-Power Converter Section item # PD4590CSV. This is only going to work if you have a lithium switch in your actual power center, shown on the picture below. It just swaps out the converter charger to make it compatible with lithium batteries.
What year and model camper do you have?
