The_Scrutineer got a reaction from Cuan in Blown Inverter (Mecer IVR-1200LBKS 1200VA + Mecer LiFePO4 200AH)A conceptual question
So far every manual I have looked at does not say "do not connect more than x AH battery to this inverter"
1.2KVA divided by 12 volts = 100amps. Does this therefore mean the max battery that can be attached is 100AH? If multiple batteries are attached in parallel would you not then have 200AH to consume, with only 100AH of ... I dont know the correct term... so will say electrical pressure
So as a thought experiment, if you have 2 x 100 liter JoJo tanks raised 2m off the ground. Each has a pipe and the two pipes run to ground level and are joined and fed into a tap
Alternatively you have 1 x 200 litre JoJo tank, raised 2m off the ground. It also has a pipe running to a tap at ground level
Would the 200 litre tank not create twice gravity fed pressure vs the 2 x 100 litre tanks?
(logic being if F= ma where Mass is the water and acceleration is gravity, with the 2 x 100 litre tanks its 100kg x 1G whereas a single tank is 200kgs x 1G.
Replace water with batteries and the tap with an inverter and conceptually an inverter has to hold back twice the electrical pressure with a 200AH battery than with 2x 100AH batteries)?

The_Scrutineer got a reaction from 87 Dream in Blown Inverter (Mecer IVR-1200LBKS 1200VA + Mecer LiFePO4 200AH)No I haven't. Looking from above and around everything is "pristine". No hints of scorching or anything else and can't smell anything burnt either.
After learning a little about BMS I figure the BMS and the inverter charge circuit had a bun fight and the inverter lost
Running the same battery on the IVR1200 MPPT everything seems to work 100%, especially around the bulk charge cut off and not trickle charging the LiFEPO4

The_Scrutineer reacted to JaseZA in Blown Inverter (Mecer IVR-1200LBKS 1200VA + Mecer LiFePO4 200AH)Correct! In fact it turns out the Mecer 200ah is just 100ah cells in parallel!
