Victron Smartsolar reports 400W and my inverter is only using 200W but the batteries do not really charge.
If I turn off the inverter they do charge. Any help on this appreciated.
More info required, the 400W will be input power to the MPPT, output will be a little lower, cable losses will add in also. The inverter, is the 200W the ac power out, dc power in will be higher, the amount depending on the model and also the type of ac load. There may not be a lot left for the batteries. Any other lads not accounted for on the dc side, Cerbo GX ?.
Thank you for the response. Details: SmartSolar 150/35. Sunwheel 3000W inverter. 3 2560Wh XZNY Lifepoe4 batties connected to busbar. I use a Kill-O-Watt meter on the load out from the inverter (AC). It reports 200W I use VictronConnect it reports 400W going in. Batteries are almost new. The issue is they are getting a minimal charge even though there is a 200W difference. Is there some setting on the SmartSolar that would help? Or should I look at the BMS and inverter?
If you are generating 400W and the battery is not being charged then the power is going somewhere. 200W is a low output for a 3000W inverter so the input power will be no load power, plus inefficiency plus 200W if the output meter is to be believed. How do you know the batteries are not being charged, are they Bluetooth or do you have a battery meter. You need independent checking of DC loads such as with a clamp meter. You have a budget system, it will not be as efficient as you may expect. If the MPPT is raising the battery volts to more than 13.5V the batteries will be charging. I doubt there is anything you can do on the MPPT settings, take a screenshot and we can check.
