    Battery not charging effectively from Panels

    Maybe I am, I thought I was way under and running over the weekend with not a heavy load but not really charging the batteries seemed strange, however I did add a refrigerator which might be the cause for draining energy down. I will play with it some more -- mainly concerned I had the settings...

    Battery not charging effectively from Panels

    Thanks for the reply, I have not seen the BMS show over voltage protection. Only an error about inconsistent current, which is apparently common and unimportant when charging from AC Not on the batteries, max was about 54.2V, goes down to about 48V when discharged. I found it interesting that...

    Battery not charging effectively from Panels

    p.s. my assumption is I have set Bulk Charging Voltage and Floating Charging Voltage too high and it is only trickling in charge, but want to double check before adjusting them.

    Adding Solar Panels to Existing System

    Thanks for the replies, I am in Thailand so the temp stays pretty high, but a cold winter morning could get down to about 10°C, I think your advice is good and I will look at adjusting my panels to give a little more safely under the inverter's max

    Adding Solar Panels to Existing System

    Thanks, so you think the 3 panels in series is too close to the inverters max voltage ... I was concerned about the higher amps and the long cabling to inverter. If I changed to the configuration you suggest, what sized wire would I need, I guess pretty small 2-3mm for the serial arrays, but...

    Adding Solar Panels to Existing System

    I am not sure which spec is the current rating, attached are specification of the panels I am looking at (the 345 watt option)

    Adding Solar Panels to Existing System

    I am adding panels to an existing inverter+battery system and have planned the panel system as follows: Existing inverter: - MPP 4kW PIP-MS4048 - Max PV Input / Output: 3000 W - Max Charging Current MPPT 60A - Max PV Input Voc, MPPT Range: 145V, 60~115V Planned panels: - BlueTech POLY 345W -...

    Please check wiring (inverter in UPS backup mode)

    I am setting up inverter/batteries in UPS/Backup mode in a little house in Thailand, this is a temporary system. I was hoping the forum could review my wiring, and also answer a couple of questions I have. The house is 220-240V 2-wire single phase, pics: Planned wiring diagram after...

    Help review UPS setup using MPP 4kW PIP-MS4048 inverter

    Am I correct that I should have a BMS in this configuration with Li-ion/LiFePo batteries?

    Help review UPS setup using MPP 4kW PIP-MS4048 inverter

    I am putting together an inverter + battery system and want to check if my plan is ok: The goal: - run load off grid power - charge batteries from grid - switch to batteries when grid power cuts ie: running as a UPS system (for the time being). The load I am anticipating is ~10-15 computer +...

    Running inverter with no solar panels, adding panels later

    I am thinking about 4000 watt initially, then adding another 4000 watt later. Am single phase in Thailand 230V/50Hz I am starting to think I could split it into two systems 1. Powers loads that need uninterrupted power, eg: computers, this would be running in online UPS mode 2. Powers loads...

    Ensuring fast switching between solar and grid

    Thanks for replies, the MPP zero transfer time inverter looks interesting, although RedTechNeck's comment about not using grid has got me thinking too. If I went zero transfer I could reduce batteries and panels to have only emergency capacity, rather than enough to power the entire load each...

    Ensuring fast switching between solar and grid

    I think you can call 'run-off-the-battery-all-the-time' UPS functionality, it seems functionally similar to an "online" UPS which does not need to switch to the inverter/battery supply when power cuts..

    Running inverter with no solar panels, adding panels later

    Thank you all for the replies, glad to hear it should not increase grid costs much. To answer why: because the grid may not be available, we get regular power cuts, am powering a number of office computers and the power cuts can be costly because of unsaved work and lost worker hours for...

    Hybrid inverter switching between solar and battery has no switch time (no power interruption)?

    Thanks for the responses, I get in now that the power merges and is shared, I sometimes see people say in this configuration the solar powers the load, and the batteries are only used when solar is not sufficient, but that statement did not seem right when the two inputs simply merge, ie I feel...

    Comparing inverters in parallel vs splitting into multiple systems

    I am planning on purchasing an off-grid system, and then increasing it's capacity in a year or so. My plan is to buy one set now, then a second set including inverter/panels/batteries later. I am currently considering whether to hook the second set into the first set with the inverters in...

    Running inverter with no solar panels, adding panels later

    I have plans to build a new solar system with hybrid inverter to be used in a new house being built, but prior to the house being built I have no place to safely install solar panels. I live in a location that experiences regular power cuts and am thinking of buying the batteries and inverter...

    Ensuring fast switching between solar and grid

    I am planning a solar system to charge 10-20 computers, ~4-5000W inverter, I strongly want uninterupted power to these computers during power cuts, but also when switching to grid when solar/battery charge is low. I am reasonably convinced I will need to run my load off batteries all the time...

    Hybrid inverter switching between solar and battery has no switch time (no power interruption)?

    I understand hybrid inverters have an internal ATS (automatic transfer switch) that can switch the load from solar/battery to grid supply when batteries are running low. How about when switching load between solar panel power and battery power, eg solar panel power is used when there is...
