The Voltronic Zoo
I just compiled a spreadsheet of what Coulomb calls "The Zoo" of Voltronic 230 Vac off-grid wall-mount inverters, with the specs that distinguish them from each other. I also give model numbers for the equivalent inverters from MPP Solar, when they exist.
It only includes currently available models, not all the past models, some of which have the same numbers as current models, but different specs!
I note that when a model has a 64V option (for maximum absorb or equalise voltage), MPP Solar sell it only with
Here's a decoder for Voltronic model numbers of the form:
Axpert www xxxx-yy pppp
contains one of the following strings:
EX = PWM
KS = PWM (equiv PIP-HS and PIP-HSP)
VP = PWM, economy (lower charge current and not parallelable) (equiv PIP-HSE)
MEX = MPPT
MKS = MPPT (equiv PIP-MS and PIP-MSP)
MKS II = MPPT 450 V (equiv PIP-MG)
VM = MPPT, economy (lower charge current and not parallelable) (equiv PIP-MSE and PIP-MSXE)
VM II = MPPT 500 V (equiv PIP-GE)
VM III = MPPT 400 V or 500 V, removable display (equiv PIP-GK)
King = MPPT, removable display (equiv PIP-MK)
Plus Duo = 2 x MPPT (equiv PIP-MSD)
Plus Tri = 3 x MPPT (equiv PIP-MST)
(digits with possible decimal point and possible "K" for kilo) = apparent power in volt-amps
(digits only) = battery voltage
is either "Plus" or not present
Plus = MPPT SCC with max Voc = 145 V, in the case where another model differs only in having a lower-voltage SCC (equiv PIP-zz
Here's a decoder for MPP Solar model numbers of the form:
xx (digits only) = true power in hundreds of watts
(digits only) = battery voltage
contains 2 or 3 (and in one case 4) of the following letters:
M = MPPT SCC (first letter)
H = PWM SCC (first letter)
G = MPPT SCC with max Voc ≥ 400 V (first or second letter)
S is meaningless (second letter)
K = Removable display (second letter)
E = Economy (lower charge current and not parallelable) (second, third or fourth letter)
P = power factor 0.8 (third letter)
D = Dual MPPTs (third letter)
T = Triple MPPTs (third letter)
X = MPPT SCC with max Voc = 145 V, in the case where another model differs only in having a lower-voltage SCC (third letter)
(1) = power factor 1, in the case where another model differs only in having a lower power factor
(64V) = has the 64 V max absorb voltage option
Here's MPP Solar's own comparison chart
Here's a decoder for Mecer (rhymes with "spacer") models of the form: [Thanks to Coulomb for the following]
possibly followed by dd
is the apparent power in kVA, usually 5 or 3
is a series code string:
M = 145 V max MPPT, PF0.8, 60 A SCC, except if manufactured between November 2017 and at least March 2018, when they became PF1.0 and 80 A SCC, and didn't bother to change the series code.
P = 145 V max MPPT, 80 A, PF1.0.
NB = PF1 450 V max MPPT, 80 A SCC.
D = PF0.8 dual MPPT (145 V max 60 A x 2)
T = PF0.8 triple MPPT (145 V max 60 A x 3)
KP = MPPT, removable display equivalent to Axpert King 5K or PIP-5048MK
K or P when following 3 seem to be MPPT, removable display equivalent to an Axpert King 3K or PIP-3024MK
when present indicates:
64 = 64 V max battery voltage on a 48 V nominal machine
24 = 24 V nominal battery voltage.
3M24 = 75 V max MPPT, 600 W solar charging.
3MPLUS24 = PF0.8 145 V max MPPT 60 A SCC.
When not present, you can assume a 48 V nominal battery voltage with 58.4 V max if x is 5, or 24 V nominal if x is 3.
There seems to be another, older pattern, e.g.
M = Mecer
5K = 5 kVA
PAR = parallel capable but not necessarily supplied with a paralleling kit
A = PF0.8
